WebJul 7, 2024 · The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Is CP CV always R? Cp-Cv = R This is the second relationship between Cp and Cv. What does it mean? WebJun 12, 2024 · Gas is 65% CO2, 35% CH3, water-saturated. My rules of thumb say stuff like Cp=(9/2)R and Cv=(7/2)R for "triatomic gas", but that doesn't help much for this gas mixture. And Cp-Cv=R gives me negative values for this particular gas, so that's out. I am within ideal gas approximation range if that helps. Thanks guys!
