Thermodynamic Processes

A rigid diatomic gas undergoes adiabatic change. Its pressure P and temperature T are related as $P \propto T^{x}$ where x is

Show answer and solution

Answer: (c)

Adiabatic: $P \propto T^{\gamma/(\gamma-1)}$ .
Rigid diatomic: $\gamma = \frac{7}{5}$ , so $x = \frac{7/5}{2/5} = 3.5$
So the answer is (c) 3.5.
