### Beginner's Guide to Propulsion

Reaction of Gases - Worksheet

1. Give one effect that the compressibility of air has on an object moving through it.

2. In the Animated Gas Lab, what happens to the volume of a gas when you freeze mass and pressure and increase the temperature?  Why does this happen?

3. When temperature and mass remain constant, what will happen to the pressure when the volume of a gas is decreased? Why?

4. Why does an increase in the mass of a gas increase the volume of that gas within the chamber?  (Temperature and pressure remain constant in this example.)

5. When pressure increases, which variables should remain constant in order to observe an increase in temperature?

6. Explain "Charles and Gay-Lussac's Law."

7. Following this thinking, if the volume of a given mass of gas is 5 cubic meters, what is the temperature?

8. Which properties depend on the amount of gas in the sample?

9. Which formula helps us find the "specific volume" of a gas?

10. Which property of a gas causes pressure within a container?
