It takes a lot of force to compress water (as with all liquids) but it can be done.Water at a depth of several thousand meters is compressed about 1% ... i.e. it is 99% of its uncompressed volume. Suppose we lowered a sturdy metal container several thousand meters below sea level, allowed it to fill with water, and then (via some clever remote device) screwed a lid into place on it.Presumably a pressure gauge inside the device would not change its reading as we brought the device back up to the surface, provided we kept the lid sealed.And presumably when we did unseal the lid, the 1% expansion of the water would produce [manifest? ] a very large unbalanced force. Is this right?

I wonder if the air could even be compressed to the point of turning to liquid air.
Only if the temperature was below -140 C, at which point the water would be well solid.

The big issue with CO2 would be solubility. (That might be a problem with any gas come to think of it.)
