2. The particles in the oxygen gas animation show many different kinds of motions. Identify three different kinds of motions/interactions you observe. Which motions create pressure on the walls of the container

Answer: Rotary, Oscillating, Reciprocating.

Oscillating creates pressure on the walls of the container

Explanation: Molecules are colliding with each other and with the wall of the inside of the container bouncing back and forth in oscillating motion. As they collide, they exert force and fill the container. Hence the Oscillating motion creates pressure from swinging of molecules from wall to wall.
