Key Concepts

Physical Properties

Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical identity. They include aspects such as melting point, boiling point, density, color, and phase, which provide information about the state and behavior of a substance under various physical conditions.

Chemical Properties

Chemical properties describe a substance's ability to undergo chemical reactions, resulting in a change in its chemical composition. These properties include reactivity with other chemicals, flammability, and tendencies to oxidize, corrode, or decompose, which indicate how a substance behaves when it interacts with other substances or under certain conditions.
