Reply to comment by Verneke in How much do water molecules move around within a stationary body of water? by KpgIsKpg

Fun fact. The speed of sound through a substance is dictated by the average speed of the molecules within that substance. Speed of sound in air is about 750mph, so the average speed of each air molecule at any given moment is 750mph.

But they only go extremely short distances before bouncing of another molecule and going another direction.

Edit: The average speed of air molecules is actually closer to 1000mph at room temperature.

Almost, but not quite. The average speed of air molecules at room temperature is 1000mph.
