States of Matter and Gas Laws

I can ______.

- Explain, in terms of collision theory why gas pressure increases when volume decreases.
- Explain, in terms of collision theory why gas pressure increases when it is heated in a rigid container.
- Explain, in terms of collision theory, why a balloon expands if it is heated.
- Explain why the Kelvin scale must be used for gas calculations instead of the Celsius scale.
- Solve a series of gas law problems involving any of the following formulas:

- P
_{1}V_{1}= P_{2}V_{2 } - P
_{1}/T_{1 }= P_{2}/ T_{2} - V
_{1}/T_{1}= V_{2}/T_{2 } - P
_{1}V_{1}/T_{1}= P_{2}V_{2}/T_{2} - PV = nRT

- Determine the mole fraction and partial pressure of a gas in a mixture.
- Apply Avogadro’s Hypothesis to solve a problem involving samples of gas at the same temperature and pressure.
- Explain how the speeds of gases differ in a mixture.
- Identify a gas by applying Graham’s Law.
- Solve a problem involving an open manometer.
