The temperature of a hypothetical gas increases to $\sqrt{2}$ times when compressed adiabatically to half the volume. Its equation can be written as

  • A
    $PV^{3/2} = \text{constant}$
  • B
    $PV^{5/2} = \text{constant}$
  • C
    $PV^{7/3} = \text{constant}$
  • D
    $PV^{4/3} = \text{constant}$
