Now before we talk about the kinetic molecular theory, let's talk about an ideal gas. Now we did ideal gas law theory. We looked at different calculations. We looked at stoichiometry deal dealing with ideal gas theory. But what we need to realize is that the ideal gas is an imaginary gas and it acts as though it is alone by behaving independently of other gases around it.
Now, ideal gases pretend as though they're the only gas within a container, that they are not influenced by any other gases around them. In reality, all containers have hundreds, thousands, maybe even millions of gas molecules moving around, bouncing into each other, affecting one another's trajectories. Some of them, if they hit hard enough and in the right spot, they can actually stick together.
Now, if we're talking about ideal gases and they're not real, how can we talk about them? Well, the kinetic molecular theory, what it does is it uses data of real gases to predict how ideal gases would behave if they existed. So even though ideal gases are not real, we can actually look at real gases around us and predict their behavior if they were around.
All right, So now that we know the usefulness of the kinetic molecular theory, click on the next video and let's take a look at an example question.
