Dear student,
 
As the pressure rises, so does the temperature, If you didn't allow the steam to vent, the pot would blow up!!
 
And for an ideal gas under constant volume, the pressure is proportional to square of speed of molecules.and pressure is proportional to average of speed of each molecule.
 
Hope this helps.
thanking you
