Thermodynamic Processes

A diatomic gas undergoes adiabatic change. Its pressure P and temperature T are related as P∝TxP \propto T^{x} where the value of x is

Show answer and solution

Answer: (a)

  1. Adiabatic: P∝Tγ/(γ−1)P \propto T^{\gamma/(\gamma-1)}.
  2. Diatomic: γ=75\gamma = \frac{7}{5}, so x=7/52/5=3.5x = \frac{7/5}{2/5} = 3.5
  3. So the answer is (a) 3.5.
