Applying pressure to a gas increases the density of the gas molecules, forcing them closer together. This compression reduces the volume and can cause the gas to transition into a liquid state, as the intermolecular forces become significant enough to overcome the kinetic energy of the molecules. The process follows the principles of the gas laws, particularly Boyle's law, which states that increasing pressure on a gas at constant temperature leads to a decrease in volume.

How does applying pressure (or compression)help in the liquefaction of a gas?
Applying pressure to a gas reduces the volume it occupies, which increases the density of the gas. This compression forces gas molecules closer together, overcoming intermolecular forces and allowing them to transition into a liquid state when the pressure exceeds the gas's critical pressure. Essentially, higher pressure facilitates the liquefaction process by enabling the gas to condense into a liquid more efficiently.
How does pressure help in liquefaction of a gas?
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.
How does applying pressure or compression help in liquification of gas?
Applying pressure to a gas decreases its volume and increases the molecular interactions among its particles. This compression forces the gas molecules closer together, which can lead to a phase change into a liquid state, especially when combined with cooling. The increased pressure overcomes the kinetic energy of the gas molecules, allowing attractive forces to dominate and facilitate liquefaction.
What are the physical quantities and the manner in which these need to be altered for liquifying gases?
To liquefy gases, key physical quantities such as pressure and temperature must be altered. Increasing the pressure of a gas can lead to liquefaction, as it forces gas molecules closer together. Simultaneously, lowering the temperature reduces the kinetic energy of the molecules, which helps them condense into a liquid state. The combination of high pressure and low temperature is essential for effective gas liquefaction.
What is the liquefaction point of oxygen gas?
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.

How ammonia gas liquefied?
Liquefaction by cooling down (lower temperature) and compression (higher pressure)
What is the liquefaction point of oxygen gas?
In order to liquify oxygen gas, the critical temperature is 154.58K (i.e., -118.57 °C) and the critical pressure is 5.043MPa.
What is difference between condensation and liquefaction?
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.
What is the favorable condition for liquefaction of gases?
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.
What do you mean by liquefaction. Discuss different ways by which liquefaction of gases can be achieved?
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.
How can gas become a liquid?
by applying pressure
Why does applying pressure help in the liquefaction of gases?
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.
Hw does a gas change into a liquid?
