Thermodynamic Processes

A diatomic gas (γ=1.4)(\gamma = 1.4) does 100 J100\text{ J} of work in an isobaric expansion. The heat given to the gas is:

Show answer and solution

Answer: (c)

  1. Isobaric: QW=CpR=γγ−1\frac{Q}{W} = \frac{C_p}{R} = \frac{\gamma}{\gamma - 1}
  2. Q=100×1.40.4=350 JQ = 100 \times \frac{1.4}{0.4} = 350\text{ J}
  3. So the answer is (c) 350 J.
