nở khối
Definition
- Noun (Technical/Scientific):
- Volume expansion: The increase in the three-dimensional size (volume) of a solid, liquid, or gas due to an external effect, most commonly an increase in temperature.
- Cubic dilatation: A physics term for the proportional change in volume of a material per degree of temperature change.
Usage Examples
- Noun:
- Sự nở khối của nước khi đóng băng có thể làm vỡ chai. (The volume expansion of water when it freezes can break a bottle.)
- Các kỹ sư phải tính toán sự nở khối của kim loại khi thiết kế cầu đường. (Engineers must calculate the volume expansion of metal when designing bridges and roads.)
- Nở khối là một hiện tượng vật lý quan trọng. (Volume expansion is an important physical phenomenon.)
Advanced Usage
- This term is primarily used in scientific, engineering, and technical contexts (physics, construction, materials science). It is not common in everyday conversation.
