Intermolecular forces act between neighboring atoms, molecules, or ions, and they can be used to explain pretty much every macroscopic property of matter! We'll be learning about the different kinds of intermolecular forces and how they affect properties such as surface tension.
The air you are (hopefully) breathing is a mixture of nitrogen and oxygen gases. We could also think of it as a solution of oxygen gas in nitrogen gas. In this section we will be learning about different types of mixtures, how to calculate concentration, and colligative properties.
