What good is it to have someone else do your work? Sure you might pass a test but you just wasted a semester on nothing if you don't learn the stuff yourself! Do your own work! If you can't do it ask the teacher about it.

Pv=nRT
Since pressure and temperature are on opposite sides of the equation, a decrease in one will result in a decrease of the other.
The best way to remember these temp. vs pressure questions is to picture a balloon. If you put a filled balloon in a refidgerator, it will shrink. Why? Because the pressure inside the ballon had dropped in comparison with that of the outside pressure (due to the change in temperature) causing the pressure outside to crush the balloon in. The exact opposite happens if you heat the balloon.
