Heat of fusion (? hfus) is used for calculations involving a phase change between solid and liquid, with no temperature change. for h2o, ? hfus=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 (? hvap) is used for calculations involving a phase change between liquid and gas, with no temperature change. for h2o, ? hvap=40.7 kj/mol. part ahow much heat is required to raise the temperature of 92.0g of water from its melting point to its boiling point? express your answer numerically in kilojoules.
