How much heat (in kJ) is required to warm 10.0 g of ice, initially at -13.0 ∘C, to steam at 109.0 ∘C? The heat capacity of ice is 2.09 J/g⋅∘C and that of steam is 2.01 J/g⋅∘C. The heat capacity of liquid water is 4.18 J/g⋅∘C. This substance has an enthalpy of fusion of 6.01 kJ/mol and an enthalpy of vaporization of 40.7 kJ/mol.
