Why is more energy required to vaporise 1kg of water than to melt 1kg of ice? (Please help, this is urgent)

The temperature change occurs from heat transfer if the ice melts and becomes liquid water. Similarly, energy is needed to vaporize a liquid, because the molecules in a liquid interact with each other via attractive forces.
