<h3>
Define Heat. What is the SI unit of Heat?</h3>
Because heat is a type of energy, the SI unit for heat is also joules (J), which is defined as the quantity of energy required to increase the temperature of a given mass by one degree. This is significant because heat is a form of energy. Heat is the result of the movement of kinetic energy within a material or an item, or from an energy source to a material or an object. Radiation, conduction, and convection are the three mechanisms through which such energy can be transferred. The joule is the S.I. unit for heat.
