Charles' Law only holds true if gases have no interactions between one another- that is to say, they are behaving like ideal gases. If they're starting to stick together, then they won't move as freely as expected, causing the observed volume to be less than what is expected.

Gases will start to behave oddly at high pressures due to how closely the molecules are being forced together. The same goes for when gases approach their condensation points.

"Liquefaction" is an odd term, but I believe it means that the gas is about to condense.

Therefore, high-pressure and near-liquid gases tend to defy Charles' Law.

I can't find a concrete source for this, however- I'll go through my textbook when I get the chance and see if I can verify what I'm saying.
