Thermodynamic Processes

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

$[\gamma = \frac{C_p}{C_v} = \frac{5}{3}$ for monoatomic gas]

Show answer and solution

Answer: (d)

At constant pressure $W = nR\Delta T$ .
At constant volume $Q = nC_v\Delta T = n\frac{3}{2}R\Delta T = \frac{3}{2}W$ (monoatomic).
So the answer is (d) $\frac{3W}{2}$ .
