Q95 / 180 · AIIMS 2019 (25 May) · Physics

Assertion : Pressure $(P)$ versus 1/volume $(V)$ graph is straight line for adiabatic process. Reason : $P V=$ constant for adiabatic process.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • Correct answer
    D
    If both assertion and reason are false.

Solution

Pressure versus $1 / V^\gamma$ is straight line. For adiabatic process, $P V^\gamma=$ constant.

Hence, the correct answer is option: 'D'.
