Thermodynamic Processes

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio of CpCv\frac{C_p}{C_v} for the gas is:

Show answer and solution

Answer: (b)

  1. Adiabatic: P∝Tγ/(γ−1)P \propto T^{\gamma/(\gamma-1)}.
  2. γγ−1=3⇒γ=32\frac{\gamma}{\gamma - 1} = 3 \Rightarrow \gamma = \frac{3}{2}
  3. So the answer is (b) 32\frac{3}{2}.
