>Would it just turn into a pressurized container full of steam?

This is the answer

>Would the water stay water but just like, really hot?

You could get this result if you add something.

If you put the water in a pressurized container, the boiling point would rise. So it wouldn’t boil at 100°C

Technically though, both of these are the case. Because as some of the water boils, it would raise the pressure, making it harder to boil the rest of the water
