Density is intensive because it is the ratio of two extensive properties that is mass to volume.
<h3>What is Density ?</h3>Density is defined as mass per unit volume. S.I unit if density is kg/m³.
It is expressed as
Density = or
Intensive property is the property which does not depend on the size of the system. Intensive property can be easily identified. Intensive property is the independent property. The size does not change in this.
Example of intensive property are Density, Freezing point, melting point, colour, Lustre, etc.
<h3>What is Extensive property ?</h3>Extensive property is the property which depend on the substance. Extensive property cannot be easily identified.
Example of extensive property length, weight, volume, mass etc.
Thus from the above conclusion we can say that Density is intensive because it is the ratio of two extensive properties that is mass to volume.

Question: The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v)
density = or
Considering that mass and volume are both extensive properties, explain why their ratio, density is intensive.
Answer: (3) ppm
Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or a solution.
Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion parts by mass of the solution.
L/s is used to express flow rate.
J/g is used to express energy per unit mass.
kPa is used to express pressure.
