8. Imagine you have two containers of gas, one labeled gas A and one labeled gas B. Gas A has an average
speed of 700 m/s and gas B has an average speed of 1100 m/s. Both containers are being held at the same
temperature. How could you match the average speeds of gas A and gas B?
A. Raise the temperature of gas B.
B. Reduce the volumes of both containers.
C. Lower the temperature of gas B.
D. Lower the temperature of gas A.
I guessed C, but it seems too easy and usually when it's easy, I'm wrong.

The correct answer is C. Lowering the temperature of gas B will cause its molecules to move more slowly, thus matching the average speed of gas A.
