[ELI5] Can one physically compress water, like with a cyclinder of water with a hydraulic press on the top, completely water tight, pressing down on it, and what would happen to the water?

Not exactly an answer to your sealed cylinder question, but a waterjet cutter compresses water very hard and makes it about 10-15% smaller before it leaves the nozzle and does the cutting.

I’m not a scientist, but a mechanical engineer.

The link gives the phase diagram for water.

As you can see, up to something between 1 GPa and 10 GPa all you have is high pressure water (for most temperatures) . Then at some point if the pressure is increased enough, it turns into a solid. Ice, but at regular temperature and insane pressure.

Water cannot be compressed. If you put it in a hydraulic press, it would be as if the water wasn’t there. The weakest part of the press would give out.

Just replying to say I’m struggling to keep up with all the replies but I am extremely grateful to all of you for making the effort, what a fantastic community this is, you are all the change we want to see in the world, if I could reply to them all then I would
