    4. The other phase change that can happen is liquid to gas. Similar to the phase change of solid to liquid, the temperature of the system does not change. All of the energy goes into the phase change.

    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...
