Condensation
Gases when kept under high pressures and as the temperature lowers turn into liquids as their energy levels are lowered and the atoms comprising of the said gas come closer to each other with slower oscillations they adopt a more viscous and fluid state which we call liquid. Some gases that are known to us on Earth for instance like Methane are actually found in a liquid and solid state under low temperatures like the planet Titan which has a unique form of geological system in that it's rocks are actually dry ice which make its hills and mountains where as the solvent on that planet exists as Methane which forms familiar sort of channels and rivers flowing like the ones we have on Earth.

By melting so the pressure pushes it until it melts and I am nine
I think because of the air and it is too much so it turns into a liquid
