CpCv , as in the case of Cp :-

Question

Cp>Cv , as in the case of Cp :- (A) more heat is required to increase the internal energy (B) heat is required to do work against external pressure also (C) more heat is required to do external work (D) more heat is required to do external work as well as for increase in internal energy

According to Mayer's formula Cp-Cv=R ∴ μ CpΔ T=μ CvΔ T+μ RΔ T Δ Qp=Δ Qv+Δ W

Q. $C_{p} > C_{v}$ , as in the case of $C_{p}$ :-

more heat is required to increase the internal energy

heat is required to do work against external pressure also

more heat is required to do external work

more heat is required to do external work as well as for increase in internal energy

According to Mayer's formula
$C_{p} - C_{v} = R$
$∴ μ C_{p} Δ T = μ C_{v} Δ T + μ R Δ T$
$Δ Q_{p} = Δ Q_{v} + Δ W$
