Pressure helps in liquefaction of a gas by reducing the volume occupied by the gas molecules, which in turn forces them closer together. When the gas molecules are compressed under high pressure, they lose their kinetic energy and slow down, allowing intermolecular forces to overcome the kinetic energy and pull the molecules closer together, leading to liquefaction.
The physical state of matter can also be changed by changing the pressure. In other words, the physical state of matter can also be changed by increasing pressure or decreasing pressure. For example, gases can be changed into liquids by increasing the pressure (accompanied by lowering of temperature). There is a lot of space between the particles of a gas. We can reduce the spaces between the particles by enclosing it in a cylinder and compressing it by pushing in the piston.
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
The temperature must be below the critical point and the phase can change to liquid by cooling the gas. If the gas is at conditions of temp and pressure below the triple point, the gas will instead be converted to a solid.
Liquefaction is the process of liquefying or making liquid.(as told by dictionary.) Liquefaction is the process where soil loses strength and acts like a liquid instead of a solid.The modern methods of cooling the gas to or below their Tc and hence of liquefaction of gases are done by Linde's method and Claude's method.

Liquefaction by cooling down (lower temperature) and compression (higher pressure)
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
The temperature must be below the critical point and the phase can change to liquid by cooling the gas. If the gas is at conditions of temp and pressure below the triple point, the gas will instead be converted to a solid.
Liquefaction is a change to a liquid from either a solid or a gas; whereas condensation is a change only from gas to liquid. Liquefaction takes place at very low temperatures(eg-Air is liquefied at -200degrees c) whereas condensation does not need such low temperatures, it occurs when water vapor changes to droplets of water on a glass of water taken out of a fridge.

Liquefaction is the process by which a solid or gas becomes a liquid, or where a solid displays the qualities of a liquid.
Preheaters are used in CO2 cylinders to prevent the CO2 gas from liquefying as it is pressurized. Liquefaction can cause blockages or malfunctions in CO2 delivery systems. Preheaters help maintain a consistent gas pressure and ensure a smooth flow of CO2.
