Task: Question Generation
Input (English): Background Paragraph: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease. 
Story: A chef is preparing ribs for his clients dinner tonight. He decides to use a pressure cooker to help keep them nice and tender. He loads the ribs in the pressure cooker and closes the latches which are relatively easy to clamp down. After cooking for a while the latches seem much tighter and the lid much harder to move.
Output (English): Will adding heat to the sealed pressure cooker increase or decrease it's internal pressure?
