Detailed explanation-1: -It has the unit joule (J) in the International System of Units (SI).
Detailed explanation-2: -The amount of energy delivered by a one watt source of power in one second is one Joule. The joule is also used to measure thermal energy. One calorie of heat is the equivalent of 4.186 J.
Detailed explanation-3: -Heat is measured in joules because James Prescott Joule experimentally showed that mechanical energy is converted to heat in 1843. For more details study thermodynamics and statistical mechanics.
Detailed explanation-4: -Heat is the form of energy and in the SI unit system, all forms of energy are measured in terms of joules. So the answer is True.
