When a pressure cooker is half filled with water, and heated to boiling point, then the pressure inside the cooker will?
decrease, since only a fraction of the water molecules has changed to vapour
remain constant, because the total number of water molecules has not changed
increase, because the water molecules can now reach every part of the sealed tube
decrease, since water boils under reduced pressure
increase, because the water vapour molecules now strike the walls of the tube more frequently because of their increased velocity
