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

PV=nRT. If you hold the Volume V constant and increased the temperature T, the Pressure P would also increase. The vessel would eventually fail and you could have an explosion.
