Ideal Gas Problems: Crash Course Chemistry
We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

Equilibrium
In this video Paul Andersen explains how equilibrium is achieved in a reversible reaction. When the rate of the forward reaction is equal to the rate of the reverse reaction the system is at equilibrium. Graphical analysis of equilibrium...

Impulse
In this video Paul Andersen defines impulse as the product of the force applied and the time over which the force is applied. The impulse of an object is equivalent to the change in momentum of the object. Several problems related to...
