A large amount of energy will be absorbed because to convert ice to water and water to vapour, we need to heat it.

1 gm of ice at  0 ⁰C  to  turn into 1 gm of vapour  at 100 ⁰C

1)   1 gm of ice takes the latent heat of fusion to melt into water.
heat energy needed = 1 gm * 334 Joules/gm = 334 J
2) 1 gm of water heats up to 100°C as water
heat energy needed = mass * specific heat * temperature difference
=  1 gm * 4.18 J/gm/°C * 100°C      = 418 Joules
3) 1 gm of water at 100°C changes physical state into vapour
heat energy needed = latent heat of vaporization
= 1 gm * 2260 J/gm = 2260 J

total energy absorbed by the water = 334 + 418 + 2260 = 3, 012 Joules
