Chem – LESSON 9: States of Matter

What is the lesson about?

This lesson is about how the properties of the small molecules relate to the properties of the large objects we interact with. We can learn how to manipulate these properties to our advantage in order to produce the exact state of any chemical we desire. At a gym we can go from a steam room to swimming pool to drinking a cup of water with ice in it. All of those were examples of one chemical H2O, but each of them had the H2O in a different state.


Why is it critical to understand?

It is critical to understand how the individual molecules of a larger picture work together in order to give a strong foundation in the concept thinking that is needed for all future lessons. Without this you will not be able to think about why things happen like they do in lessons like chemical equations, gas laws, solutions, and equilibrium. If you miss the fundamental understanding of how matter works and forms then the rest of chemistry will seem like a random string of pointless formulas and concepts that have nothing to do with each other. Create a mental video from this lesson that will carry you through how everything is related to the interactions of the different molecules.
