Interpretation:
Molar enthalpy of fusion of methanol is to be explained..
Concept introduction:
Molar enthalpy of fusion: The heat required to melt one mole of a solid substance is called its molar enthalpy (heat) of fusion

Answer to Problem 80A
It means that 3.22 kJ of energy extracted from 1 mole of liquid methanol to cause it to freeze and become 1 mole of solid methanol.
Explanation of Solution
Since
Therefore, in order to freeze 1 mole of methanol extract 3.22kJ of energy. And conversely, add 3.22kJ of energy to one mole of solid methanol to cause it to melt and become one mole of liquid methanol.
