6. We used the constant volume heat capacity, Cv, when we talked aboutthermodynamic cycles. It acts as a proportionality constant between energy andtemperature: dU = C₁dT.You can also define a heat capacity for constant pressure processes, Cp. You can thinkof enthalpy playing a similar role to energy, but for constant pressure processesδαρC = (37) - SupСратP=атStarting from the definition of enthalpy, H = U + PV, find the relationship between Cyand Cp for an ideal gas.
