Thermodynamic Processes

For a monoatomic gas, work done at constant pressure is W. The heat supplied at constant volume for the same rise in temperature of the gas is

Show answer and solution

Answer: (d)

  1. At constant pressure W=nRΔTW = nR\Delta T.
  2. At constant volume Q=nCvΔT=32nRΔT=32WQ = nC_v\Delta T = \frac{3}{2}nR\Delta T = \frac{3}{2}W (monoatomic, Cv=32RC_v = \frac{3}{2}R).
  3. So the answer is (d) 3W2\frac{3W}{2}.
