Study Notes

Intensive Properties

Depend on the type of matter within a sample, not on the amount present.
Useful for identifying substances.
Examples include density, melting point, color, boiling point of water, ductility, malleability, and odor.

Extensive Properties

Depend on the specific sample or quantity of matter.
Not useful for identifying substances.
Examples include mass, volume, length, temperature, and width.

Key Examples of Intensive Properties

Density: Defined as mass per unit volume; calculated by dividing mass by volume.
Melting Point: The specific temperature at which a solid transitions to a liquid; characteristic of a substance.
Color: Descriptive physical property that provides visual information about an object.
Boiling Point of Water: The temperature at which water changes from liquid to gas; a specific characteristic.
Ductility: The ability of a substance to be drawn into wires; indicates malleability.
Malleability: The capacity of a substance to be rolled or hammered into thin sheets.
Odor: Related to the ability of a substance to stimulate the sense of smell.

Key Examples of Extensive Properties

Mass: Total quantity of matter within an object, irrespective of its forces or volume.
Volume: Measurement of space occupied by an object; calculated as length x width x height.
Length: A quantitative measure; does not help in identifying materials.
Temperature: Reflects the average kinetic energy of particles in matter; sometimes depends on the amount of substance.
Width: Measures how wide something is; similar to length, not helpful for identification.
