Question

How does applying pressure help in the liquefaction of a gas

Answer 1

Pressure, volume and temperature help in liquefaction of gases. Pressure brings close to molecules of a gas that are far apart from each other. When more and more pressure is applied on gas molecules they come closer to each other so inter molecular forces start producing between gas molecules. Molecules shape become bipolar electrons and nucleus carrying protons change molecules into positive and negative poles. This factor helps in liquefaction of gases.

Answer 2

Explanation:

When gases are compressed, the pressure applied on the molecules is very high and the molecules come very close to each other. ... This is because the molecules of gases are far apart from each other whereas the molecules of a liquid are close to each other. Thus pressure helps in the liquefaction of gases.
