Application of Kinetic-Molecular Theory to the Gas Laws

The empirical observations of gas properties as expressed by the various gas laws are readily understood in terms of the kinetic-molecular theory. The following examples illustrate this point  

An increase in volume at constant temperature causes pressure to decrease. A 

A temperature increase at constant volume causes pressure to increase. An 

A sample of U2 gas initially at STP is compressed to a smaller volume at constant temperature. What effect does this change have on (a) the average kinetic energy of the molecules, (b) then-average speed, (c) the number of collisions they make with the container walls per unit time, (d) the number of collisions they make with a unit area of container wall per unit time  

Analyze We need to apply the concepts of the kinetic-molecular theory of gases to a gas compressed at constant temperature.
