2. Common examples include boiling point, melting point, and color.
3. They are contrasted with extensive properties, which do depend on the amount of matter present.
4. Intensive properties are useful for identifying substances because they do not change with sample size.
5. These properties can be combined to form other intensive properties through mathematical operations.
