Question

explain briefly, how gases can be liquified?

Answer 1

Gases can be liquefied by

1. By applying high pressure. As gases are highly compressible, on applying high pressure, the molecules of a gas would come close, intermolecular forces would increase and it will condense into a liquid.
2. By lowering the temperature. Gases can be converted into liquids by simple cooling. At very low temperatures, the gases convert to liquids.
