And let's say you're using a specific kind of kettle that's made of 3-inch metal. The kettle has a latch on it, that when shut, makes the kettle completely airproof, waterproof, gasproof, etc.
You open the latch until the water starts to boil and steam comes out. Then you shut the latch. What would happen?

Edited by Chaz: 5/13/2013 9:30:33 PMPressure inside the kettle would increase since the water is changing to gas but staying in a confined space. Eventually the force due to this pressure would probably break the kettle open. EDIT: Wait no the boiling point of the water would increase actually.
