An ultrasound uses sound waves to produce images of a baby.
Examples of intensive properties include:
- Boiling point
- Density
- State of matter
- Color
- Melting point
- Odor
- Luster
- Hardness
- Ductility
- Malleability
Intensive properties can be used to help identify a sample because these characteristics do not depend on the amount of sample, nor do they change according to conditions.
Extensive Properties
Extensive properties do depend on the amount of matter that is present. Examples of extensive properties include:
- Volume
- Mass
- Size
- Weight
- Length
While extensive properties are great for describing a sample, they aren't very helpful identifying it because they can change according to sample size or conditions.
Way To Tell Intensive and Extensive Properties Apart?
One easy way to tell whether a physical property is intensive or extensive is to take two identical samples of a substance and put them together.
Explanation and Examples of Physical Properties
If this doubles the property (e.g., twice the mass, twice as long), it's an extensive property. If the property is unchanged by altering the sample size, it's an intensive property.
