Question

Define Thermal Expansion! ​

Answer 1

Answer:

Thermal expansion describes the tendency of an object to change its dimension either in length, area or volume due to heat. Heating up a substance increases its kinetic energy.

Depending on the type of expansion thermal expansion is of 3 types– Linear expansion, Area expansion, and Volume expansion.

Answer 2

• Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance.
