Answer:
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.
