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?

Answer 1

You’d get what is called a BLEVE (blev-E)! Boiling liquid expanding vapor *explosion*. The pressure builds and builds until the container fails or ruptures. There are a lot of crazy firefighting videos about them.
