WebHelium can also be used as a working fluid. It is inert and has a high specific heat capacity (5.19 kJ/kg K) [45]. However, it is has a low density compared with other working fluids and therefore needs to be pressurized to increase its volumetric heat capacity (4.2×10 3 J/m 3 K at 1800K and 30 bar [45] ). WebAnswer: at constant volume [Cv] it is 3/2 R at constant pressure [Cp] it is 5/2 R. This is ideal gas behavior. values at -150C are 3.01 and 4.99 cal/mole deg which come pretty close, calc 2.98 and 4.97.
