You have two equal sized boxes, A and B. Each box contains an ideal gas. A pressure gauge in A reads 0.20 atm, and a gauge in B reads 0.04 atm. This is all that we know about the gasses.

1. There are more molecules in A than in B
A. True      B. False      C. Could be true, but not necessarily so

2. The molecules in A are moving faster than the molecules in B
A. True      B. False      C. Could be true, but not necessarily so

3. The temperature in A is higher than in B
A. True      B. False      C. Could be true, but not necessarily so

4. The molecules in A are heavier than those in B
A. True      B. False      C. Could be true, but not necessarily so

5. The molecules in A have more kinetic energy than those in B
A. True      B. False      C. Could be true, but not necessarily so

Now you have the same equal-sized boxes and each contains the N molecules of an ideal gas. A pressure gauge in A reads 0.20 atm, and a gauge in B reads 0.04 atm. This is all that we know about the gasses.

1. The molecules in A are moving faster than the molecules in B
A. True      B. False      C. Could be true, but not necessarily so

2. The temperature in A is higher than in B
A. True      B. False      C. Could be true, but not necessarily so

3. The molecules in A are heavier than those in B
A. True      B. False      C. Could be true, but not necessarily so

4. The molecules in A have more kinetic energy than those in B
A. True      B. False      C. Could be true, but not necessarily so
