WebThe ratio of the speciﬁc heats, also called adiabatic index, is given by g = Cp Cv = 1 + 2 f. The ratio of the speciﬁc heats is 5/3 for monatomic ideal gas and 7/5 for diatomic gas. Its value for air is 1.4. This ratio is used to deﬁne (1) adiabatic process pVg = const, and (2) speed of sound in gases v = p gRT/M.
