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

PV/T= ideal gas law
in the question the volume is constant which gives P/T, it implies P=kTpresssure is directly proportional to the temperature. increase in the temperature increases pressure because of the increased velocity as stated
