Question

What is heat energy?

Answer 1

Heat is a form of energy that always travels from a hotter substance to a colder substance. Temperature is a measure of the energy that matter contains, or how hot or cold it is. Heat energy is very useful to all living things. We use heat energy for cooking food, to warm ourselves, and to make electricity

Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
