During an adiabatic process, the pressure of a gas is proportional to the cube of its temperature. The value of \(C_p / C_V\) for that gas is
- A \(\frac{7}{5}\)
- B \(\frac{4}{5}\)
- C \(\frac{5}{3}\)
- D \(\frac{3}{2}\)
Answer & Solution
Correct Answer
(D) \(\frac{3}{2}\)
Step-by-step Solution
Detailed explanation
In adiabatic process \(p V^{\prime}=k\) Given, \(\quad p \propto T^3\) or \(p=k T^3\) \(\begin{aligned} & =k\left(\frac{p V}{R}\right)^3 \\ & =\left(\frac{k}{R^3}\right) p^3 V^3 \\ \text { or } \quad p & =\left(\frac{k}{R^3}\right) p^3 V^3 \\ \Rightarrow \quad p^2 V^3 & =k…
