Heat of fusion (ΔHfusΔHfusDeltaH_fus) is used for calculations involving a phase change between solid and liquid, with no temperature change. For H2OH2O, ΔHfus=6.02 kJ/molΔHfus=6.02 kJ/mol. Specific heat capacity (CCC) is used for calculations that involve a temperature change, but no phase change. For liquid water, C=4.184 J/(g⋅∘C)C=4.184 J/(g⋅∘C). Heat of vaporization (ΔHvapΔHvapDeltaH_vap) is used for calculations involving a phase change between liquid and gas, with no temperature change. For H2OH2O, ΔHvap=40.7 kJ/molΔHvap=40.7 kJ/mol. Part A How much heat is required to melt 78.0 gg of ice at its melting point? Express your answer numerically in kilojoules.
