|When you roll one ball into another ball that
is sitting still, the ball that was originally still will start rolling
- but the other ball will slow down. We can think of a hot gas as many tiny balls, moving very
quickly and a cool gas as many tiny balls, moving very slowly.
This way of thinking about gasses is often called the "Billiard
Ball Model" of gas.
What would happen if you mixed a hot gas and a cool gas together? Try to explain your answer using the Billiard Ball Model.
What would happen if you mixed a hot gas with twice as much cool gas? Try to explain your answer using the Billiard Ball Model.
