Extensive quantity: its magnitude is additive for subsystems (volume, mass, etc.)
Intensive quantity: the magnitude is independent of the extent of the system (temperature, pressure, etc.)
There are also physical quantities that can be classified as neither extensive nor intensive, for example angular momentum, area, force, length, and time.
