Explain Thermal Expansion​

Answer 1

Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature. ... The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature.
