Question

Match these items. Match the items in the left column to the items in the right column.1. freezing equals melting 2 . allows molecular attractions to increase 3. P x V = k 4. V/T = k 5. temperature at which vapor pressure = atmospheric pressurea. normal boiling pointb. Boyle's Lawc. Charles' Lawd. Cooling effecte. phase equilibrium

Answer 1

1↔e 2↔d 3↔b 4↔c 5↔a

Step-by-step 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.
