Assertion (A): Latent heat falls as the temperature rises towards the critical point.
Reason (R): The liquid and vapour become more alike as the critical point is approached.

  • A.A is true but R is false
  • B.A is false but R is true
  • C.Both A and R are true, and R is the correct explanation of A
  • D.Both A and R are true, but R is not the correct explanation of A

Answer: C

Both are true and the reason gives the cause: the two phases become identical at the critical point, so no energy is needed to convert one into the other and the latent heat goes to zero. The saturation curve terminates at that same point.
