MATTER AND ENERGY. 2.2 - Physical and Chemical Properties. The characteristics that we use to identify matter and distinguish them from one another are called properties. We group these properties into two broad categories: Physical properties and Chemical properties. Physical properties of matter are usually those that we can observe with our senses.
