Webenergy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature. Hence, heat … WebHeat and temperature are related and often confused. More heat usually means a higher temperature. Heat (symbol: Q) is energy.It is the total amount of energy (both kinetic and potential) possessed by the molecules in a piece of matter.Heat is measured in Joules.
