Chitosan specific heat capacity
WebApr 9, 2024 · The heat capacity ratio (gamma, γ) for an ideal gas can be related to the degrees of freedom ( f ) of gas molecules by the formula: γ = 1 + 2 f or f = 2 γ − 1 The specific heat of gas at constant volume in terms of degree of freedom 'f' is given as: C v = ( f 2) R Also, C p − C v = R Therefore, C p = ( f 2) R + R = R ( 1 + f 2)
