Water Pressure

>if fluids are in-compressible, how can water be kept under pressure?

Usually by sex or drugs. Flouride is a hell of a drug! I'm rick James bitch!

>My desk isn't compressible, how come when I bang my head on it, it doesn't explode?

Why has nobody asked this yet.

If you have a big steel casing, but completely filled with water, and you froze it, would it freeze, breaking the container? Or would it stay liquid at any temperature.

If it got cold enough it would freeze and the expansion would crack the casing. That's why people in cold climates are supposed to leave their tap running a bit if they lose heating.

that's what she said

Fluids aren't incompressible. At high enough pressures everything is compressible.

Infinite gravity applied from all sides would probably compress some water.
