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 ).
