Particles can have translational, rotational, and/or vibrational kinetic energy, depending on the state of matter. Temperature is a measure of the average kinetic energy of the particles in a substance. Heat is thermal energy that transfers into or out of a system. Heat can transfer by conduction, convection, or radiation.

This transfer of energy between systems is what we call heat. Temperature measures the average kinetic energy or motion of these particles. All matter contains moving particles with kinetic energy, which contributes to its thermal energy.
