Temperature Measures Average Kinetic Energy

The hotness of a material is related to the average kinetic energy of the submicroscopic particles within that material. In general, the hotter the material, the greater the average kinetic energy of its particles. We say "average" kinetic energy because the particles are all moving at different speeds--some fast some slow. Duration: 1:40.
