Unformatted text preview: gas particles are in constant random motion. The particles are small and the space between them is large. They move with different speeds in different directions. They follow the Physics learned in mechanics, colliding with each other and the walls of their container creating pressure. As a result, only the average velocity can be calculated. However, if direction is included then the average would be zero. All the particles are moving in different directions, and every particle would be cancelled by another that is doing the opposite. If the velocities are squared then the plusses and minuses that indicate direction would be eliminated, but the magnitude would be squared. The aver...
