AP Chemistry Update

Today students were working on concepts from Chapter 5. After finishing up our discussion of the Chapter 5 Classwork from Friday's class, I explained the answers to the AP Multiple Choice Questions (MCQ's) related to Chapter 5. If you need to see the answers to these MCQ's you can look at this document.

These are some of the important concepts that were discussed in class today:

• If two gases are at the same temperature, then they have the same average kinetic energy.
• If two gases at the same temperature have different molar masses, the one that has a smaller molar mass has the largest average molecular speed.
• Gases will be most likely to deviate from ideal behavior at low temperatures and high pressures.
• The volume of one mole of gas at standard temperature and pressure (273 K, 1 atm) is 22.4 L.

The homework for Wednesday's class is to answer the Free Response Questions (FRQ's) related to chapter 5.
