In this lesson, we will learn about density and volume in chemistry. We will learn that density is the measure of the mass of a substance compared to its volume. We will use the density to measure the properties of a substance. Water when it freezes forms a solid ice, which actually has a density less than that of liquid water. This means that ice floats on water and allows life to exist on earth. We discuss exactly why this occurs in water.
