which one is thermal contraction?

• less temperture less volume

• the measure of the average kinetic energy.

• more temperature more volume

what is Temperature:

• the measure of the average kinetic energy

• the measure of the potential energy

• When  temperature increase particles will collide more so the volume of a material will increase.
