Pressure affects changes of state of state by forcing the molecules closer together.
Explanation:
The strength of intermolecular forces of attractiondecreases in the order:
Solids > liquids > gases.
So liquids and gases have weaker intermolecular forces of attraction than solids. Also, their molecules are farther apart from each other than in solids.
If you increase the pressure on a gas, its molecules are brought in close contact with each other. The attractive forces eventually become strong enough to hold the molecules close together, and the gas condenses to the liquid state.
