Study Notes
Chemical Properties
- Chemical properties describe how a substance interacts during chemical reactions.
- Changes to a substance's composition are required to observe chemical properties.
- Examples of chemical properties include reactivity with oxygen, water, acids, or bases.
Physical Properties
- Physical properties can be observed and measured without changing the substance's composition.
- Examples of physical properties include color, luster, temperature, and mass.
Extensive Properties
- Extensive properties depend on the amount of matter present.
- Volume, weight, and Inertia are examples of extensive properties.
