what is thermal expansion?
Answers
Thermal expansion is the tendency of matter to change it's shape and size in response to change in temperature.
Answer:
the general increase in the volume of a material as its temperature is increased.
Explanation:
It is usually expressed as a fractional change in length or volume per unit temperature change; a linear expansion coefficient is usually employed in describing the expansion of a solid, while a volume expansion coefficient is more useful for a liquid or a gas. If a crystalline solid is isometric (has the same structural configuration throughout), the expansion will be uniform in all dimensions of the crystal. If it is not isometric, there may be different expansion coefficients for different crystallographic directions, and the crystal will change shape as the temperature changes.
