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)

  1. For PVx=PV^{x} = constant: C=Cv+R1−xC = C_v + \frac{R}{1 - x}.
  2. Monatomic Cv=32RC_v = \frac{3}{2}R, x=3x = 3: C=32R−R2=RC = \frac{3}{2}R - \frac{R}{2} = R
  3. So the answer is (d) R.
