energy, 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.
Energy Storage Capacity
Thermal capacitance is connected to the energy storage capacity and assumes no energy losses. It is defined as the heat flow necessary to change the temperature rate of a medium by one unit in one second: (5.124) C t h = q ( t) d θ ( t) d t = d Q ( t) d t d θ ( t) d t = d Q d θ. The SI unit for thermal capacitance is N-m-K −1 (or J-K −1 ).
