What will be the quantity of heat required when 4 kg of water converts into water vapour???

Answers (1)

As we know that the Latent heat of vapourisation of water = 2260 kJ/kg (Assuming that the water is at 100o C)


To convert 4kg of water into vapour, total heat needed = 4×2260 = 9040 kJ  (Phase transformation from liquid to vapour)
