A solid is a state of matter characterized by structural rigidity and resistance to changes in shape or volume.
30 सेकंड में शब्द
- A state of matter with fixed shape and volume.
- Particles are packed closely together.
- One of the three basic states of matter.
Overview
- 1概述：固体（Solid）是物质在特定温度和压力下呈现的物理状态之一。与液体和气体不同，固体的原子或分子在空间中呈规则或不规则的排列，且相互作用力较强，这使得固体能够保持一定的形状和体积，而不随容器改变。
उदाहरण

该工厂主要处理固体废物。
formalThe factory mainly processes solid waste.
这块巧克力已经融化，不再是固体了。
informalThis chocolate has melted and is no longer a solid.
固体物理学是研究固体结构及其性质的学科。

अक्सर इससे भ्रम होता है
Hard object refers to the physical hardness of an item. Solid refers to the state of matter regardless of how hard it is.
Object is a general term for any physical thing. Solid is a specific classification of matter based on its state.

How to Use It
इस्तेमाल की जानकारी
The word '固体' is neutral and commonly used in both academic and daily life. It is often used in technical contexts like environmental science or physics. Avoid using it to describe something that is simply 'hard' if you are not referring to its physical state.
सामान्य गलतियाँ
Learners sometimes use '固体' to mean 'hard' (e.g., 'this bed is solid' instead of 'hard'). Remember that '固体' is a state of matter, not a quality of hardness. Ensure you use it as a noun or a technical modifier.
Tips
Use in scientific contexts
When discussing physics or chemistry, use '固体' to refer to the state of matter. It is a precise term compared to general words like 'hard things'.
Do not confuse with hard
Remember that '固体' refers to the state (solid), not necessarily the hardness (硬度). Some solids are soft.
Environmental awareness in China
The term '固体废物' (solid waste) is frequently used in Chinese environmental policies and news. It is a key term in modern urban management.
शब्द की उत्पत्ति
The character '固' implies firm or fixed, while '体' refers to body or substance. Together they describe a substance with a fixed body/shape.
सांस्कृतिक संदर्भ
In China, the term '固体废物' is highly associated with national environmental protection campaigns. It highlights the importance of recycling and waste management in modern Chinese society.
याद रखने का तरीका
Think of a brick: it keeps its shape because it is a solid. The word '固' implies 'fixed' or 'firm'.
अक्सर पूछे जाने वाले सवाल
4 सवाल不一定。虽然大多数固体具有一定的硬度，但有些固体（如橡皮泥或海绵）在受力时会发生形变，它们依然属于固体范畴。
可以。通过加热，固体可以发生熔化现象转变为液体，例如冰融化成水。
主要区别在于分子间的距离和作用力。固体分子紧密排列且位置相对固定，而气体分子间距离很大，可以自由运动。
你可以直接将其作为名词使用，例如“这种物质在室温下是固体”，也可以作为形容词修饰，如“固体肥料”。
खुद को परखो
冰在零度以下通常保持___状态。
冰是水的固态形式。
