Chemical Engineering - Stoichiometry - Discussion

An ideal gas can be liquefied through a process of cooling and compression. As the gas is cooled and its pressure increased, the molecules lose kinetic energy, allowing them to come closer together and form a liquid.

It should be in this way - ' An ideal gas cannot be liquefied, because.

No, An Ideal gas cannot be liquefied because the intermolecular forces in an ideal gas are negligible.

Gases liquefy when their component molecules come into contact and interact with each other; this will always happen before absolute zero because real gas particles have volume. But an ideal gas has particles of zero volume, and no inter-molecular interactions, by definition. Therefore it can't liquefy.
