Derive a relation between cp and cv
WebUsing nRT = P V, the P versus V relationship follows: P Vγ = const00. The work done by a gas in an adiabatic expansion follows from dQ = 0: dW adiabatic = −dU = −C V dT and then W adiabatic = −C V Z dT = −C V 4T . 9 WebApr 7, 2024 · This gives a major impact on the final result Cp. The expression of a calorically perfect gas is generalized as follows: e = CvTh = CpT 2. Thermally Perfect Gas Thermally perfect gas is present in thermodynamics equilibrium. It does not react chemically.

WebJan 15, 2024 · In order to derive an expression, let’s start from the definitions. Cp = (∂H ∂T)p and CV = (∂U ∂T)V The difference is thus Cp − Cv = (∂H ∂T)p − (∂U ∂T)V In order to evaluate this difference, consider the definition of enthalpy: H = U + pV Differentiating this yields dH = dU + pdV + Vdp http://www.hep.fsu.edu/~berg/teach/phy2048/1202.pdf
