Physics problem

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. Lower the temperature of gas B.

B. Lower the temperature of gas A.

C. Reduce the volumes of both containers.

D. Raise the temperature of gas B.
