WebApr 9, 2024 · The Heat Capacity at Constant Pressure (C p)/ Heat capacity at Constant Volume(C v) The isentropic expansion factor is another name for heat capacity ratio that is also denoted for an ideal gas by γ (gamma). Therefore, the ratio between C p and C v is the specific heat ratio, γ. So, \[\gamma = \frac{C_{p}}{C_{v}}\]
