Thermodynamic Processes question from NEET 2016 (Phase 2)

Q224NEET 2016 · PHASE 2Difficult

Thermodynamic Processes

One mole of an ideal monatomic gas undergoes a process described by the equation PV3 = constant. The heat capacity of the gas during this process is

Show answer and solution

Answer: (d)

For $PV^{x} =$ constant: $C = C_v + \frac{R}{1 - x}$ .
Monatomic $C_v = \frac{3}{2}R$ , $x = 3$ : $C = \frac{3}{2}R - \frac{R}{2} = R$
So the answer is (d) R.
