During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of $\frac{C _{p}}{C _{v}}$ for the gas isNEET 2013 (All India)

Options:

Answer:

Solution:

According to question, $p \propto T^{3} p V = n RT and p \propto T^{3} P \propto (p V)^{3} \Rightarrow p^{2} V^{3} = constant p V^{3/2} = constant ∵ p V^{γ} = constant ∴ γ = \frac{3}{2}$
