Cv value thermodynamics

WebSep 12, 2024 · CV = 3 2R. It is independent of temperature, which justifies our use of finite differences instead of a derivative. This formula agrees well with experimental results. In the next chapter we discuss the molar specific heat at constant pressure Cp, which is always greater than CV. Example 2.4.1: Calculating Temperature WebqV = n CV∆T This value is equal to the change in internal energy, that is, qV = n CV∆T = ∆U We know that for one mole (n=1) of an ideal gas, ∆H = ∆U + ∆ (pV ) = ∆U + ∆ (RT) = ∆U …
