Answer to Question #147579 in Physics for Meron

Question

Is it increase in kinetic energy that causes a body to get hotter or is it the hotness of the body that causes it's increase in kinetic energy?

Answer 1

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.
