The molar heat of fusion of lithium metal is 3.00 kJ/mol, whereas its heat of vaporization is 147 kJ/mol. a. Why is the heat of vaporization so much larger than the heat of fusion? O Since conversion from a liquid to a gas breaks many more intermolecular forces than conversion from a solid to a liquid, it requires much more energy. O Since conversion from a solid to a liquid breaks many more intermolecular forces than conversion from a liquid to a gas, it requires much less energy. O Since conversion from a solid to a liquid breaks many more intermolecular forces than conversion from a liquid to a gas, it requires much more energy. O Since conversion from a liquid to a gas breaks many more intermolecular forces than conversion from a solid to a liquid, it requires much less energy. b. What quantity of heat would be needed to melt 1.00 g lithium at its normal melting point? Нeat - J What quantity of heat would be needed to vaporize 1.00 g lithium at its normal boiling point? Heat = What quantity of heat would be evolved if 1.00 g lithium vapor condensed at its normal boiling point? Heat =
