![]() A chemical change might also result in the formation of a precipitate, such as the appearance of a cloudy material when dissolved substances are mixed. The formation of gas bubbles is often the result of a chemical change (except in the case of boiling, which is a physical change). For example, the freezing point of a substance is a physical property: when water freezes, it’s still water (\text Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance’s chemical identity. Intensive properties, such as density and color, do not depend on the amount of matter. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. ![]() chemical property: Any characteristic that can be determined only by changing a substance’s molecular structure.Īll properties of matter are either extensive or intensive and either physical or chemical.physical property: Any characteristic that can be determined without changing the substance’s chemical identity.extensive property: Any characteristic of matter that depends on the amount of matter being measured.intensive property: Any characteristic of matter that does not depend on the amount of the substance present.Chemical properties can be measured only by changing a substance’s chemical identity.Physical properties can be measured without changing a substance’s chemical identity.Intensive properties, such as density and color, do not depend on the amount of the substance present.Extensive properties, such as mass and volume, depend on the amount of matter being measured.All properties of matter are either physical or chemical properties, and physical properties are either intensive or extensive.
