Which of the following is insensitive to changes in pressure ?
Correct answer: D. Both B. and C.
- A. Heat of vaporisation
- B. Melting point
- C. Heat of fusion
- D. Both B. and C.
Explanation
The melting point and heat of fusion are comparatively insensitive to pressure, whereas the heat of vaporisation changes appreciably with pressure because vapour volume changes greatly. Therefore both B and C apply.
