There are two separate containers of gases, where one contains oxygen and the other contains chlorine. a. If the temperature, pressure and volume are the same in both containers, which molecule would collide more often? b. If you wanted to minimize the number of collisions between oxygen molecules in one of the containers, which properties of the system would you change? List three variables and describe how you would change each one?
