Increasing or decreasing the pressure can change the state of matter. Applying pressure and reducing temperature can liquefy gases.

For an example, Solid carbon dioxide (CO2) is stored under high pressure. Solid CO2 gets converted directly to gaseous state on decrease of pressure to 1 atmosphere* without coming into liquid state. This is the reason that solid carbon dioxide is also known as dry ice.
