1. C) Identify and apply the relationships among the variables that affect the volume of an ideal gas (pressure,
temperature, & number of molecules).
2. A) Identify and apply the relationships among the variables that affect the volume of an ideal gas (pressure,
temperature, & number of molecules).
3. B) Identify and apply the relationships among the variables that affect the volume of an ideal gas (pressure,

4. A) Identify and apply the relationships among the variables that affect the volume of an ideal gas (pressure,
temperature, & number of molecules).
5. D) Explain the relationship among the variables that affect the volume of an ideal gas occupies in terms of the
kinetic molecular theory.
6. C) Explain the relationship among the variables that affect the volume of an ideal gas occupies in terms of the
kinetic molecular theory.
7. B) ) Use equal volumes of different gases under the same conditions of temperature and pressure to compare
numbers of molecules and their relative masses (Avogadro’s Principle).
8. A) ) Use equal volumes of different gases under the same conditions of temperature and pressure to compare
numbers of molecules and their relative masses (Avogadro’s Principle).
9. A) ) Use equal volumes of different gases under the same conditions of temperature and pressure to compare
numbers of molecules and their relative masses (Avogadro’s Principle).
10. F) Use equal volumes of different gases under the same conditions of temperature and pressure to compare
numbers of molecules and their relative masses (Avogadro’s Principle).
11. A) Use equal volumes of different gases under the same conditions of temperature and pressure to compare
numbers of molecules and their relative masses (Avogadro’s Principle).
12. F) Relate the temperature of a gas to the average kinetic energy of the particles comprising that gas.
13. C) Compare the average speed of gas particles for different gases at the same temperature.
14. B) Differentiate between a scientific law, a hypothesis and a theory.
15. Compare the average speed of gas particles for different gases at the same temperature.
The gases meet closer to the HCl side of the tube because the HCl molecules have a greater molecular mass
compared to the NH3 molecule and hence have a lower average speed at the same temperature.
