Solids, liquids, and gases are familiar to students as the different states of matter. Why are some substances gases and some solid at room temperature? This exercise helps students explore the basic concepts behind intermolecular bonding and how it affects states of matter and the properties of materials. One important concept that this exercise emphasizes is that molecules come in many different sizes. The size of the molecules is one of the most important determinants of the properties of a substance.
