A building contractor needs 500 sheets of drywall. Which is the most cost-effective way to buy them?

The greater the speed of gas particles in a container, the greater is the pressure. When you increase the temperature of a given volume of gas; you are actually increasing the kinetic energy of the molecules. The incessant battering into the walls of the container causes an increase in pressure within the container. And the more pressure it exerts, the more collisions between the gas particles takes place. It also follows the combined gas law wherein pressure is directly proportional to the temperature and inversely proportional to volume.
