Explain Cp-Cv=R whatcis the value of R . explain |
|
Answer» This is called as Mayer's formula.Derivation:ΔU = ΔQ + ΔW ΔU = Cv ΔT (At pressure is constant)ΔQ = Cp ΔT (At pressure is constant)ΔW = -P ΔV (Negative since the calculation been COMPLETE)PV = RT (1 mole of gas)Because of pressure is constant, R is also constantChange in V will make change in TPΔV = R ΔTCv ΔT = CpΔT - RΔTDivided by ΔTCv = Cp - RCp - Cv = RHope this helps you.☆cHeeRs!☆ |
