Answer:
Most of us use the word 'heat' to mean something that feels warm, but science defines heat as the flow of energy from a warm object to a cooler object. ... Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases.
Heat is a transfer of thermal energy caused by a difference in temperature. This temperature difference is also called a temperature gradient. Since heat is a movement of energy, it is measured in the same units as energy: joules
