If Gas is the only state of matter where you can change the density with pressure, how can you pressurise liquids like water?

Question

I know that solids and liquids can’t change density without changing their molecular structure, so how do things like oil pressure and water pressure exist?

Answer 1

Very simply Gas isn’t the only state of matter that can be compressed / have their density changed.

Liquids can be compressed as well without changing their molecular structure as well as solids.

Just because you get a handful of dirt and compress it into a solid lump of dirt it hasn’t changed the molecular structure of the soil, it’s simply compacted it and thus made it more dense
