"Webb25 jan. 2024 · The ratio of heat capacity at constant pressure (C P) to heat capacity at constant volume (C V) is defined as heat capacity ratio. The isentropic expansion factor, commonly known as heat capacity ratio, is indicated by γ for an ideal gas (gamma). As a result, specific heat ratio, γ is equal to ratio of C P to C V, i.e. γ = C P ⁄ C V. " - Problems on specific heat
