I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Let Professor Dave run you through the details.

We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

In this video, we will look at what dilutions are in chemistry, how to calculate them using a very easy equation and even extending to multiple dilutions which are called serial dilutions. Dilution is the process of adding water (or...
