What happens if you boil water in a closed 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.
Does boiling takes place at room temperature?
False, Boiling takes place at a temperature where the vapor pressure of the liquid is equal to the local atmospheric pressure. Evaporation takes place at all temperatures at a rate that depends on temperature and the existing difference from saturated vapor pressure.
