CHEMISTRY Pre-AP Unit 12: Gas Laws

Goal: The student should be able to:

1. State the relationship between the pressure of a gas and volume of a gas.

2. Write the equation for and apply Boyle's Law in solving problems and state the conditions under which Boyle's Law can be used.

3. State the relationship between the temperature of a gas and the volume of a gas.

4. Write the equation for and apply Charles' Law in solving problems and state the conditions under which Charles' Law can be used.

5. State the relationship between the temperature of a gas and the pressure of a gas.

6. Write the equation for and apply Gay-Lussac’s Law in solving problems and state the conditions under which the Gay-Lussac Law can be used.

7. Correct the pressure of a certain volume of a gas when it is collected over water or when it is known to be saturated with water vapor.

8. Apply the combined gas lawin working problems including stoichiometry at nonstandard conditions of temperature and pressure.

9. State the effect of pressure and temperature on the density of a gas.

10. Correct the density of gas to STP given the volume, temperature and pressure.

11. Explain and apply the Ideal Gas Law.

12. Use the Ideal Gas Law to compute molecular mass.

13. List the properties of real gases, which lead to deviations from the model of an ideal gas and thus deviation from the Ideal gas- laws.
