Learning Goal:To calculate the total energy required to convert a solid to agas using heat capacity, heat of fusion, and heat ofvaporization.The amount of heat required to melt one mole of a solid iscalled the heat of fusion (AHfus). The amount of heatrequired to vaporize (boil) one mole of a liquid is called theheat of vaporization (AHvap). The heat of fusion and theheat of vaporization can be used to calculate the amount ofheat needed to melt or vaporize, respectively, a given amountof substance.For example, the heat of fusion for H2O is 6.02 kJ/mol,which means that 6.02 kJ of heat is needed to melt a mole ofice. Twice as much heat is needed to melt twice as much ice,as shown here:2.00 mol x 6.02 kJ/mol = 12.0 kJ%3DPart CHow much heat is required to boil 81.5 g of water at its boiling point?Express your answer numerically in kilojoules.> View Available Hint(s)kJ

To calculate the total energy required to convert a solid to gas using heat capacity, heat of fusion, and heat of vaporization. The amount of heat required to melt one mole of a solid is called the heat of fusion (AHfus). The amount of heat required to vaporize (boil) one mole of a liquid is called the heat of vaporization (AHvap). The heat of fusion and the heat of vaporization can be used to calculate the amount o heat needed to melt or vaporize, respectively, a given amoI of substance. For example, the heat of fusion for H2O is 6.02 kJ/mol, which means that 6.02 kJ of heat is needed to melt a mole ice. Twice as much heat is needed to melt twice as much ice as shown here: 2.00 mol x 6.02 kJ/mol = 12.0 kJ %3D
