Boiling water in an open and closed beaker

put a lid on the pot, and it will boil a little bit faster (because the lid keeps cold air from coming in). The boiling point might rise a little over the normal boiling point because the #pressure in the house will #increase a little bit as you boil off the #water.

Heating liquid in a #closed #constant #volume container

If the #container is closed, all vapor generated by #boiling will stay in the container. If it is at constant volume, the pressure will rise in it. That is what happens in a pressure cooker at the beginning of the cooking process. The pressure rises, and so the water in it will not boil at the normal boiling point. Instead, it will start boiling at a higher temperature. In a pressure cooker, there is a valve to release gas when the pressure reaches a certain value. Without the #valve, the pressure would continue to rise until it stops boiling again, or the pressure #cooker will #explode.
