Question
How does applying pressure (or compression) help in the liquefaction of a gas?
✓

Answer

There is a lot of space between the particles of a gas. If enough pressure is applied to the gas, it gets highly compressed. The particles of gas get so close together that they start attracting each other sufficiently to form a liquid. And we say that the gas has liquefied.
