Question

The molar specific heat at constant pressure of an ideal gas is $(7 / 2) R$. The ratio of specific heat at constant pressure to that at constant volume is\

Professor PC Thomas Classes · Answer

(b) : Molar specific heat at constant pressure\ $C_{P}=\frac{7}{2} R \quad 	herefore \quad C_{V}=C_{P}-R=\frac{7}{2} R-R=\frac{5}{2} R$.\ $	herefore \quad \frac{C_{P}}{C_{V}}=\frac{(7 / 2) R}{(5 / 2) R}=\frac{7}{5}$\
