Explicação 凝結 in your Level:

At the A1 level, '凝結' (gyōketsu) is a very difficult word that you probably won't need for daily life. It is a 'science' word. Instead, you should learn simpler words like '水' (mizu - water) or '雲' (kumo - cloud). If you see '凝結' in a book, just remember it means 'gas turning into water.' Think about a hot shower: the steam turns into little water drops on the mirror. That process is '凝結.' In easy Japanese, we might say '水蒸気が水になる' (suijōki ga mizu ni naru - water vapor becomes water). Focus on learning the kanji for water and clouds first. '凝結' is for when you become a scientist or a weather reporter later! For now, if you see it, just think: 'Ah, water is forming from the air.' It is much more formal than what people say at home.

At the A2 level, you are starting to learn more about the world around you in Japanese. '凝結' (gyōketsu) is a formal word for 'condensation.' You might see it in a basic science textbook or a weather report on TV. It is a combination of two kanji: '凝' (congeal) and '結' (tie/result). You don't need to use it in conversation yet, but you should recognize it. A common example is how clouds are made. When warm air goes up and gets cold, the water in the air 'condenses' (凝結する). If you are at home and see water on your window, Japanese people usually use a different word, '結露' (ketsuro). '凝結' is the 'classroom' word. Try to remember that '凝結' is a process where something invisible (gas) becomes something you can see (liquid).

At the B1 level, you should be able to understand '凝結' (gyōketsu) when reading news articles or watching educational videos. This word is a 'suru-verb,' so you will often see it as '凝結する' (to condense). It is primarily used in scientific contexts. For instance, when explaining the water cycle (水循環), '凝結' is the key term for the step where vapor turns into clouds. You should also start to notice the difference between '凝結' and '凝固' (gyōko - freezing/solidification). While '凝結' is about gas becoming liquid, '凝固' is about liquid becoming solid. If you are describing a scientific experiment in Japanese, '凝結' is the correct term to use. You might also hear it in weather forecasts when they talk about fog (霧) forming during the night.

At the B2 level, '凝結' (gyōketsu) is a word you are expected to know and use in formal or academic settings. As an upper-intermediate learner, you should understand the technical nuances. For example, '凝結核' (gyōketsukaku) refers to condensation nuclei, which are essential for cloud formation. You should be able to explain the physical process using this term: '水蒸気が凝結して小さな水滴になります' (Water vapor condenses and becomes small water droplets). At this level, it is important to distinguish '凝結' from '結露' (surface condensation) and '凝縮' (general condensation/compression). '凝結' is specifically about the phase change from gas to liquid or solid. You might encounter this word in environmental discussions, engineering documents, or advanced science materials. It carries a formal, objective tone.

At the C1 level, you should have a nuanced command of '凝結' (gyōketsu) and its related terminology. You should be comfortable using it in professional presentations, academic writing, or high-level discussions about physics and meteorology. Beyond the basic 'gas to liquid' definition, you might explore its rarer metaphorical uses in literature, where it describes the 'solidification' of abstract concepts like 'power' or 'will' into a tangible form. You should also be familiar with related technical terms like '凝結熱' (heat of condensation) and how it relates to latent heat (潜熱). At this level, you should be able to debate environmental issues, such as how pollutants act as '凝結核' and affect rainfall patterns, using '凝結' with precision and ease. Your understanding should include the historical context of the word as a Meiji-era scientific translation.

At the C2 level, '凝結' (gyōketsu) is a tool for precise scientific and philosophical expression. You understand that while it primarily denotes the phase transition from gas to liquid, its kanji roots allow for a poetic interpretation of 'concentration' and 'crystallization' of thought. You can effortlessly distinguish between '凝結', '凝縮', '凝固', and '液化' in a technical paper, choosing the exact term that fits the thermodynamic process being described. You might analyze how the term is used in classical modern literature to describe the chilling atmosphere of a scene or the crystallization of a character's resolve. Your mastery allows you to use '凝結' in complex grammatical structures, such as describing the '凝結点' (condensation point) of exotic gases or the '凝結作用' (condensing action) in industrial chemical engineering, all while maintaining the appropriate formal register.

凝結 em 30 segundos

A formal/scientific term for condensation, specifically the phase change from a gaseous state to a liquid or solid state due to cooling or pressure.
Commonly used in meteorology to describe cloud and fog formation, often appearing in textbooks, news, and technical documents rather than casual speech.
Distinct from 'ketsuro' (everyday surface dew) and 'gyōko' (freezing), focusing on the physical transition of vapor into droplets.
Functions as a noun or a suru-verb (凝結する), frequently associated with technical terms like 'condensation nuclei' (凝結核) and 'latent heat' (潜熱).

The Japanese word 凝結 (ぎょうけつ - gyōketsu) is a technical and formal term primarily used in the fields of physics, meteorology, and chemistry. At its core, it describes the physical process of phase transition, specifically when a substance changes from a gaseous state to a liquid or solid state. While English speakers might simply use the word 'condensation' for a variety of situations, Japanese distinguishes between the general scientific process (凝結) and the specific everyday occurrence of moisture forming on a cold surface (結露 - ketsuro). Understanding 凝結 requires looking at its kanji: 凝 (gyō), meaning to congeal, freeze, or concentrate, and 結 (ketsu), meaning to tie, bind, or result in. Together, they paint a picture of molecules binding together and concentrating into a denser form.

Scientific Context: In meteorological terms, 凝結 is the process by which water vapor in the air turns into liquid water droplets, forming clouds or fog. This typically happens when air cools or when the amount of water vapor reaches its saturation point.

空気中の水蒸気が冷えて凝結し、雲ができる。(Water vapor in the air cools and condenses, forming clouds.)

Beyond science, 凝結 can occasionally be used metaphorically to describe the 'solidification' of ideas, feelings, or power, although this is much rarer than its scientific application. It implies a high degree of concentration and a change in state from something ephemeral to something tangible. In industrial settings, it might refer to the coagulation of particles in a liquid, such as in water treatment or food production. For a Japanese learner, the challenge lies in distinguishing 凝結 from its synonyms. While 凝縮 (gyōshuku) also means condensation, it often carries a nuance of 'compression' or 'concentration' (like condensed milk), whereas 凝結 is strictly about the phase change itself. In everyday life, if you see water on your window in winter, you would use 結露, but if you are explaining the physics behind it in a classroom, you would use 凝結.

Historically, the term has been used in Japanese academic writing since the Meiji era, when Western scientific concepts were being translated into kanji-based compounds. The choice of '凝' suggests a sense of 'stiffening' or 'becoming firm,' which accurately reflects the increase in density during condensation. When using this word, one should be aware that it functions as a 'suru-verb' (凝結する), allowing it to describe the action of condensing as well as the noun form of the process. In modern Japanese, its frequency is moderate, appearing most often in educational materials, news segments about the weather, and technical manuals involving HVAC or refrigeration systems.

Using 凝結 correctly involves understanding its role as a technical noun. It is most frequently paired with the particle 'が' (ga) to indicate the subject that is condensing, or used with 'する' (suru) to describe the process. Because it is a formal word, it is rarely found in casual conversation between friends unless they are discussing a specific scientific topic. Instead, it populates textbooks, academic papers, and formal presentations.

Grammatical Pattern: [Substance] + が + 凝結する (Substance condenses). For example: 水蒸気が凝結する (Water vapor condenses).

高度が上がると気温が下がり、水蒸気の凝結が始まる。(As altitude increases, temperature decreases, and the condensation of water vapor begins.)

Another common usage is the compound noun 凝結核 (gyōketsukaku), which refers to 'condensation nuclei'—the tiny particles like dust or salt around which water vapor condenses to form clouds. This is a crucial term in meteorology. You might also encounter 凝結点 (gyōketsuten), meaning the 'condensation point,' the specific temperature at which a gas begins to turn into a liquid. In these cases, 凝結 acts as a modifier for the following noun.

In a professional setting, such as an engineering firm, one might say: '配管内での凝結を防ぐ必要があります' (It is necessary to prevent condensation within the piping). Here, 凝結 is used to describe a technical problem that needs solving. The word carries a weight of precision and objectivity. If you were to use '結露' in this context, it would sound slightly more informal, like you are talking about the visible droplets rather than the physical process itself. Therefore, choosing 凝結 signals that you are discussing the phenomenon from a physical or engineering perspective.

While you won't hear 凝結 at a coffee shop or during a casual chat about the weather, it is a staple of specific environments. The most common place is the classroom. From elementary school science (rika) through university physics, 凝結 is the standard term for explaining the water cycle. Students learn how water evaporates from the ocean, rises, and then undergoes 凝結 to form clouds. If you watch NHK's educational programming or documentaries about nature, you will hear this word frequently.

Media Usage: Weather forecasts on TV often use '凝結' when explaining the formation of thick fog (霧 - kiri) or specific types of clouds. It adds a layer of scientific authority to the forecast.

今夜は放射冷却により、水蒸気が凝結して濃い霧が発生する見込みです。(Due to radiative cooling tonight, water vapor is expected to condense and thick fog will form.)

Another sphere where 凝結 is prevalent is in the manufacturing and construction industries. Engineers discussing the design of insulation or the prevention of moisture damage in buildings will use this term. For instance, in a meeting about building materials, an architect might discuss the '凝結防止' (gyōketsu bōshi - prevention of condensation) properties of a new type of glass. In this context, it is a technical requirement. Furthermore, in the chemical industry, the term is used when discussing the recovery of solvents or the cooling of gases in reactors. If you work in a STEM field in Japan, 凝結 will be part of your daily professional vocabulary.

Finally, you might encounter the word in literature, particularly in science fiction or older 'Meiji-era' novels where the author wishes to use sophisticated, kanji-heavy language to describe the atmosphere. A writer might describe a character's breath '凝結する' in the cold air to create a more clinical or detached tone compared to the more common '白くなる' (turning white). Overall, 凝結 is a word of the 'intellect' and 'industry,' marking the speaker as someone with technical knowledge or a formal communicative intent.

The most frequent mistake learners make with 凝結 is confusing it with its close relative, 結露 (ketsuro). While both involve condensation, their usage is strictly divided by context. 結露 is used for the visible droplets on surfaces (like a cold beer can or a window), whereas 凝結 is the name of the physical process itself. If you say '窓に凝結がついている' (There is 凝結 on the window), it sounds unnatural; you should say '窓に結露ができている' or '窓が結露している'.

Comparison: 凝結 (Gyōketsu): The process of gas → liquid. (Scientific focus)
結露 (Ketsuro): The result of moisture on a surface. (Everyday focus)

Another common error is mixing up 凝結 with 凝固 (gyōko). 凝固 refers to solidification, specifically from a liquid to a solid (like water freezing into ice or blood clotting). While 凝結 can technically include gas-to-solid transitions in some scientific definitions, in general Japanese, it is almost exclusively used for gas-to-liquid. Using 凝結 to describe water freezing is a major mistake; you must use 凝固 or the simpler 凍る (kōru).

× 液体が凝結して氷になる。
○ 液体が凝固して氷になる。(The liquid solidifies/freezes into ice.)

Lastly, learners sometimes use 凝縮 (gyōshuku) interchangeably with 凝結. While 凝縮 is also 'condensation,' it is much broader. 凝縮 can mean 'condensing' a long story into a short one, or 'condensing' a liquid to make it stronger. 凝結 is strictly a physical phase change. You can 'gyōshuku' (condense) your thoughts, but you cannot 'gyōketsu' them. If you are talking about physics, 凝結 is usually the safer, more specific term for the phase change from gas to liquid.

To master 凝結, one must understand its place within a cluster of related scientific and everyday terms. Japanese is very specific about phase changes and states of matter. Depending on the level of formality and the specific physical process, you might choose a different word.

Synonym: 結露 (Ketsuro): Usage: Everyday life. Specifically refers to dew forming on windows, walls, or cold containers. Example: '冬は窓の結露がひどい' (Condensation on the windows is bad in winter).
Synonym: 凝縮 (Gyōshuku): Usage: Scientific and metaphorical. Means to condense or concentrate. Often used for 'condensed' versions of things. Example: 'エッセンスを凝縮する' (To condense the essence).
Synonym: 凝固 (Gyōko): Usage: Scientific. Means solidification or freezing. Used for liquid → solid. Example: '溶岩の凝固' (Solidification of lava).

雲の形成は凝結、氷の形成は凝固、窓の滴は結露。(Cloud formation is gyōketsu, ice formation is gyōko, window drops are ketsuro.)

In addition to these, there is 液化 (ekkia), which literally means 'liquefaction.' While 凝結 is the process of a gas turning into a liquid due to cooling, 液化 is the broader term for turning any gas into a liquid, often through pressure (like 'liquid petroleum gas' - LPG). If you are talking about industrial gases in tanks, 液化 is the term to use. If you are talking about the natural process of rain forming in the sky, 凝結 is the more appropriate choice.

For learners, the best approach is to categorize these words by their 'state transition' and 'formality.' 凝結 is 'Gas to Liquid' and 'High Formality/Scientific.' By keeping this mental map, you can avoid the awkwardness of using a textbook word in the kitchen or a kitchen word in a lab report.

How Formal Is It?

Curiosidade

The kanji '凝' is also used in 'katakori' (shoulder stiffness - 肩凝り), implying that your muscles have 'congealed' like ice!

Writing the kanji 疑 instead of 凝. → 凝
疑 means 'doubt'. 凝 has the ice radical. They look similar but have different meanings.
Using 凝結 for 'condensed milk'. → 濃縮 (nōshuku)
Condensed milk is thickened by evaporation/concentration, not by gas turning into liquid.
Using 凝結 as an i-adjective. → 凝結した (gyōketsu shita)
It is a noun/suru-verb, so you must use the 'shita' or 'suru' form to describe something.

Dicas

Science vs. Daily Life

Always use 結露 (ketsuro) for windows and 凝結 (gyōketsu) for clouds or lab experiments. This is the #1 rule for this word.

The Suru-Verb Form

Remember that 凝結 can be a verb. '水蒸気が凝結する' is the most natural way to describe the action.

Radical Recognition

The 冫 (ice) radical on the left of 凝 is a huge hint. It tells you the word is related to cold or freezing.

Learn the Pair

Learn 凝結 (gas to liquid) and 凝固 (liquid to solid) together. They are the 'science pair' of phase changes.

Weather Keywords

When you hear 'housha reikyuu' (radiative cooling), expect to hear 'gyōketsu' or 'kiri' (fog) soon after.

The Knot Mnemonic

The 結 (ketsu) in gyōketsu means 'to tie.' Think of vapor being 'tied' into water droplets.

Professional Use

If you work in construction, use 'gyōketsu boushi' (condensation prevention) to sound professional in meetings.

Literary Flair

In a C2 essay, use 凝結 to describe a 'crystallization' of ideas to impress your readers.

Not for Clots

Don't use 凝結 for blood clots. Use 凝固 (gyōko) or 凝集 (gyōshū). Using gyōketsu for blood is scientifically inaccurate in modern Japanese.

Compound Power

Compounds like 凝結核 are more common in writing than the standalone verb 凝結する.

Mnemônico

Imagine a 'GYO' (giant) 'KETSU' (kettle) where the steam 'condenses' back into water. Gyo-Ketsu!

Associação visual

Picture a cloud (gas) being tied (結) together into a tight, frozen (凝) ball of water.

Desafio

Write a three-sentence explanation of how rain is formed using the words: 水蒸気 (suijōki), 凝結 (gyōketsu), and 雨 (ame).

Origem da palavra

Composed of Sinitic roots (Kango). '凝' (gyō) stems from a root meaning water freezing or congealing. '結' (ketsu) stems from a root meaning to tie a knot or bring to a conclusion.

Significado original: To congeal and tie together; to form a solid result from a fluid or ephemeral state.

Sino-Japanese (Kango).

Contexto cultural

No specific sensitivities; it is a neutral scientific term.

English speakers often use 'condensation' for both the science and the window dew. In Japanese, using the 'wrong' word (gyōketsu instead of ketsuro) sounds like you're reading a manual.

No, while it is most commonly used for water vapor in meteorology, it can apply to any gas turning into a liquid or solid. For example, the condensation of nitrogen or oxygen in a lab setting is also called 凝結.

Technically, that is 凝結, but in daily conversation, you should say 'メガネが曇る' (megane ga kumoru). Using 凝結 would sound like you are giving a physics lecture.

It is a 'condensation nucleus.' It's a tiny particle like dust, salt, or smoke that gives water vapor a surface to cling to so it can turn into a droplet. Without these, clouds wouldn't form easily.

They are related. 凝結 is the scientific process name. 結露 is the specific word for that process happening on a surface (like a window). Use 結露 for housework and 凝結 for science.

It's 凝. It has 16 strokes. The left part is the 'ice' radical (冫), and the right part is 'Gyou' (疑 - doubt/stiff). It's quite complex!

No. For condensed milk, the word is '加糖練乳' (katō rennyū) or just 'コンデンスミルク'. The process of making it is '濃縮' (nōshuku - concentration), not 凝結.

Yes, especially when distilling liquids. When the vapor cools down and turns back into liquid in the condenser, that is 凝結.

The most direct opposite in a scientific context is 蒸発 (jōhatsu - evaporation) or 気化 (kika - vaporization).

Yes, it releases 'latent heat' (潜熱 - sen-netsu). This is why the air can sometimes feel slightly warmer when a lot of condensation happens, like during cloud formation.

It usually appears at the N2 or N1 level because of its technical nature and the complexity of the kanji.
