Thermodynamic Processes

The ratio of work done by an ideal rigid diatomic gas to the heat supplied by the gas in an isobaric process is

Show answer and solution

Answer: (b)

  1. Isobaric: WQ=nRΔTnCpΔT=RCp\dfrac{W}{Q} = \dfrac{nR\Delta T}{nC_p\Delta T} = \dfrac{R}{C_p}.
  2. Rigid diatomic: Cp=72RC_p = \dfrac{7}{2}R.
  3. WQ=27\dfrac{W}{Q} = \dfrac{2}{7}, so the answer is (b).
