What do you mean by Intensive and Extensive Properties?

Intensive Property:
An intensive property is a physical property of a system that does not depend on the system size or the amount of material in the system. I.e. An intensive quantity (also intensive variable) is a physical quantity whose value does not depend on the amount of the substance for which it is measured. Intensive property is also known as Bulk Property.

Examples of intensive properties include:
Temperature
Chemical Potential
Density
Specific Gravity
Viscosity
Velocity
Electrical Resistivity.

Extensive Property:
An extensive property of a system does depend on the system size or the amount of material in the system.

Examples of extensive properties include:
Mass
Volume
Entropy
Enthalpy
Energy
Stiffness
Particle Number
