for the math problem, all i can say is cr@p! i should know it, but i dont! ah! i hafta review! (i hate it when school starts and u have to jumpstart yourself)
as for the air, i'm pretty sure that cold air is heavier, because the molecules dont move as fast as warm air, which causes it to sink. try it. turn on the AC in your house. which is cooler, the floor or the ceiling? (answer is the floor)
