Unformatted text preview: 1 Friday Sept. 23, 2011 Todays Lecture Gases 5.6 Kinetic Theory of Gases 2 Kinetic Molecular Theory of Gases: simple model used to explain experimental observations about gas behavior Postulates: Due to large interparticle distances, their volume maybe neglected The collisions of the particles with the walls of the container give rise to pressure The particles do not exert forces on each other The average kinetic energy of a gas particle is directly proportional to the temperature (Kelvin) 3 consider a single particle of mass m and moving with a velocity u in a cube with sides L assume elastic collisions what is the force of collision with walls? mu is the momentum of the particle u (mu) F ma m t t = = = = = = = = = = = = L x y z 4 Summary of Concepts Behind the Kinetic Model Derive an equation for the change in momentum of a particle impinging on one set of parallel walls. Derive an equation for the force a particle impinging on one set of parallel walls. Equation for the total force of a particle impinging on all 6 walls....
