Eli5 what would happen if you had water in a completely sealed container and brought it past boiling temp

Question

Would it just turn into a pressurized container full of steam? Would the water stay water but just like, really hot?

In: 98

Answer 1

That is exactly what a pressure canner/instant pot does. The contents reach a temperature higher than boiling, high enough to cook faster and or/sterilize the food.

Fun fact: you can use an instant pot as an autoclave.
