- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given: Latent heat of vaporization Lv=22.6×105 J kg-1 Mass of water, m=100 kg and temperature of vapour T=100 °C. The relation of heat and latent heat of vaporization is given as,Q=mLv Q=100×22.6×105=22.6×107 J
