Study Notes
Extensive Properties
- Depend on the amount of substance present.
- Examples include size, weight, and length.
- Mass is specifically identified as an extensive property.
Intensive Properties
- Do not depend on the amount of substance present.
- Characteristics such as melting point, temperature, and color are intensive properties.
Chemical Properties
- Relate to a substance's ability to undergo chemical changes.
- Flammability, reactivity, and acidity are notable examples.
- Water reactivity and heat of combustion also qualify as chemical properties.
Physical Properties
- Can be observed without changing the composition of matter.
- Include texture, density, and solubility.
- Boiling point, melting point, and odor are specific physical properties.
Changes in Matter
- Physical changes do not affect the identity of the substance; examples include boiling water and freezing juice.
- Chemical changes result in the production of new substances and can include reactions that produce odor or color changes.
- The formation of rust exemplifies a chemical change.
Characteristics of Changes
- Freezing point represents the physical change when water turns into ice.
- Chopping wood, bending metal, and cutting a cake are all examples of physical changes.
- A chemical change occurs when sugar and water create caramel under heat.
Summary of Properties
- Combustibility is identified as a chemical property, contrasting with physical properties.
- The identity of substances remains unchanged during physical property observations.
