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 ).
