1. freezing equals melting - phase equilibrium

2. allows molecular attractions to increase - pressure cooling effect

3. PV=k - Boyle's Law

4. V/T=k - Charles' Law

5. temperature at which vapour pressure = atmospheric pressure - normal boiling point

Explanation:

Phase equilibrium is the stage at which the rate of freezing equals the rate of melting.

Pressure cooling effect allows molecular attractions to increase.

Boyle's Law states that at constant temperature, the pressure and volume vary with each other:

PV = constant (k)

Charles' Law states that at constant pressure, the volume and temperature vary with each other:

V/T = constant (k)

The temperature at which vapour pressure is equal to the atmospheric pressure is called the normal boiling point.

3 hours because it is a decent distance.
