Thermodynamic Processes

A diatomic gas undergoes adiabatic change. Its pressure pp and temperature TT are related as p∝Txp \propto T^{x}, where xx is

Show answer and solution

Answer: (d)

  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 (d) 3.5.
