How does temperature relate to kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance; higher temperature means higher average kinetic energy.

What happens to the kinetic energy of molecules as temperature increases?

Back

As temperature increases, the kinetic energy of the molecules also increases, causing them to move faster.
