The latent heat of vaporisation of water is more than latent heat of fusion of ice, because
On vaporisation much larger increase in volume takes place
Increase in kinetic energy is much smaller on boiling
Kinetic energy decrease on boiling
Volume decreases when the ice melts
Answer (1)
The latent heat of vaporisation of water is more than latent heat of fusion of ice because on vaporisation much larger increase in volume takes place.
