How much heat energy, in kilojoules, is required to convert 60.0 g of ice at −18.0 ∘C to water at 25.0 ∘C ?

Specific heat of ice: S-ice=2.09 J/(g⋅∘C) Specific heat of liquid water: S-water=4.18 J/(g⋅∘C) Enthalpy of fusion (H2O(s)→H2O(l)): ΔHfus=334 J/g Enthalpy of vaporization (H2O(l)→H2O(g)): ΔHvap=2250 J/g
