a Calculate the heat required to melt 5 50 g of benzene at its normal melting point Heat of fusion benzene 9 92 kJ mol Heat b Calculate the heat required to vaporize 5 50 g of benzene at its normal boiling point Heat of vaporization benzene 30 7 kJ mol Heat k c Why is the heat of vaporization more than three times the heat of fusion O More energy is required to overcome the forces holding the molecules together in the liquid state to g than to just allow the molecules to begin mov O Forces holding molecules in the liquid state are much stronger than in the solid state O In the liquid state intermolecular forces must be broken while in the solid state intramolecular forces must be broken
