Question

What is the energy in kj/mol required to melt 1 mole of a solid? Select one:

a. Molar heat of freezing

b. Molar heat of fission

c. Molar heat of vaporization

d. Molar heat of fusion

e. Molar heat of condensation?

Answer 1

Explanation:

Every substance has a unique value for its molar heat of fusion, depending on the amount of energy required to disrupt the intermolecular forces present in the solid. When 1 mol of ice at 0°C is converted to 1 mol of liquid water at 0°C, 6.01 kJ of heat are absorbed from the surroundings.
