Heat is a form of energy that makes any object hot or cold. It is also called thermal energy. Thermal energy is the total energy (kinetic, vibrational, and rotational) of all the individual molecules in which the given object is made. Heat is measured by the temperature effect it produces in material bodies. When a body is heated its energy increases, and? when it is cooled its energy decreases. Most substances increase their size on heating and decrease their size on cooling. Let's test yourself with the heat and temperature trivia quiz.
