When V is constant, the increased T will increase the v of moving molecules, and therefore the KE. Then the P they exert outward is greater.

1. Different volumes result in different P-T diagrams.
2. The "V" lines don't really connect to the origin, because the volume can't be 0 when there are fluid molecules.

is a sealed utensil for cooking food under steam pressure. When heat is supplied, the water inside the cooker vaporizes, and the steam is produced. The steam is periodically released through a valve to maintain the operating pressure inside the cooker.
