Answer

At higher pressures the gas particles occupy a significant portion of the gas volume, which makes the actual volume greater than that predicted by the Ideal Gas Law. At lower temperatures, the collisions between gas particles occur with lower average kinetic energies and the weak attractions between particles becomes significant.

Work Step by Step

The particles spend more time interacting with each other and spend less time colliding with surfaces. This makes the pressure lower than that predicted by the Ideal Gas Law.
