Heat of fusion (ΔHfus) is used for calculations involving a phase change between solid and liquid, with no temperature change. For H2O, ΔHfus=6.02 kJ/mol. Specific heat capacity (C) is used for calculations that involve a temperature change, but no phase change. For liquid water, C=4.184 J/(g⋅∘C). Heat of vaporization (ΔHvap) is used for calculations involving a phase change between liquid and gas, with no temperature change. For H2O, ΔHvap=40.7 kJ/mol. How much heat is required to boil 77.5 g of...
