1↔e  2↔d  3↔b  4↔c  5↔a

Explanation:

1↔e

freezing equals melting means the rate of freezing becomes equals to rate of melting in a solid-liquid phase-change reaction.This happens at phase equilibrium.

Solid  ⇄  Liquid

2↔d

Molecular attractions increase when a substance undergoes cooling as temperature is reduced.More temperature implies less molecular attraction.

3↔b

Boyle's law gives the pressure-volume relation at constant temperature for a fixed amount of ideal gas.

4↔c

Charles law gives temperature-volume relation at constant pressure for a fixed amount of ideal gas.

5↔a

Normal boiling point is the temperature at which vapor pressure becomes equal to atmospheric pressure.
