Final answer:
Chemical properties describe how a substance can change into different substances during a chemical reaction, while physical properties can be measured without changing the substance's chemical identity.
Step-by-step explanation:
Chemical properties describe a substance's capacity to undergo certain chemical transformations that result in different substances. These properties, such as flammability and reactivity with water, are only observed when a substance undergoes a chemical change. On the other hand, physical properties can be observed or measured without changing the chemical identity of the substance. These include properties like mass, color, volume, and density. For instance, pure copper has the physical property of being a reddish-brown solid, whereas its ability to dissolve in dilute nitric acid to produce a blue solution and a brown gas is a chemical property.
