How much heat (in kilojoules) is required to warm 11.0 g of ice, initially at -14.0 ∘C, to steam at 112 ∘C? The heat capacity of ice is 2.09 Jg−1∘C−1 and that of steam is 2.01 Jg−1∘C−1.

Answer 1

find the energy (heat) for each step
... the mass of H2O is constant

warm ice to 0ºC

melt ice

warm water to 100ºC

boil water

warm steam to 112ºC
