We are just starting the Gases unit. Here are the big picture questions that I would like you to keep in mind while we’re working through this unit:
- Why are certain gases better suited for specific uses?
- How can you handle gases safely?
- What is the difference between a real gas and an ideal gas?
In addition, here is a summary of what you are responsible for in this unit:
| # | Objective | Must-do Activities | Videos |
| 1 | Associate the use of certain gases in various applications with their chemical reactivity | Chemical Reactivity assignment | Reactivity |
| 2 | Explain the behavior of a gas using kinetic theory | KMT Worksheet | KMT |
| 3 | Apply the general gas law (P1V1/n1T1 = P2V2/n2T2) |
Gas Laws Worksheet
Boyle’s Law lab |
Pressure, Real vs. Ideal, General gas law, Boyle, Charles, Gay-Lussac, Avogadro |
| 4 | Apply the ideal gas law (PV = nRT) |
Gas Laws Worksheet
