Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.

I think That thermal expansions is when you heat something the particals expand, and when you cool down the thing the particals grow closer together.

Thermal expansion is when a liquid (such as water) expands by heat.

I think that thermal is heat that expands from the changes you make to it, because if you make heated particles cooler then they will grow closer together and move slower.When you heat them up again they expand and move faster.
