What is thermal energy?

Answer 1

Thermal energy refers to the internal energy of an object or substance due to the movement of its particles. It is a form of kinetic energy that arises from the random motion and vibrations of atoms and molecules within a material. The temperature of an object or substance is directly related to its thermal energy, with higher temperatures corresponding to greater thermal energy. Thermal energy can be transferred between objects through conduction, convection, or radiation.
