Educational worksheet on the properties of gases, including comprehension, true-false, and matching exercises for students.

Final Answer:
Gases are easily compressed, or squeezed into a smaller volume because of the large spaces between particles in a gas. The four variables used to describe a gas are pressure, (P), volume (V), temperature (T), and number of moles (n).
You can use kinetic molecular theory to predict and explain how gases will respond to a change in conditions. Doubling the amount of gas in a rigid container doubles the pressure. You can raise the pressure exerted by a contained gas by decreasing its volume. As the temperature of an enclosed gas decreases, the pressure decreases.
