The energy associated with the motion of particles in a substance is called

heat

Explanation:

Heat is what a living being feels at a high temperature. Physics understands heat as the energy that is transferred from one system to another or from one body to another, a transfer linked to the movement of molecules, atoms and other particles.

It is important to keep in mind that bodies do not have heat, but internal energy. When a part of this energy is transferred from one system or body to another that is at a different temperature, it speaks of heat. Heat transfer will occur until the two systems are at the same temperature and the so-called thermal equilibrium is reached.
