The latent heat of vaporisation__________________?
Correct answer: B. All A., B. & C.
- A. Decreases with increased temperature
- B. All A., B. & C.
- C. Becomes zero at the critical point
- D. Decreases as pressure increases
Explanation
Latent heat of vaporisation decreases as temperature and pressure rise, because the liquid and vapour become more alike. It falls to zero at the critical point, so all three statements are valid.
