Gamma for non linear triatomic gas
Webgamma function, generalization of the factorial function to nonintegral values, introduced … WebThe departure from this model in the case of non-linear polyatomic molecules indicates vibrational involvement. The constant pressure specific heat is related to the constant volume value by C P = C V + R. The ratio of the specific heats γ = C P /C V is a factor in adiabatic engine processes and in determining the speed of sound in a gas.
