Mass, volume, entropy and internal energy are called the extensive properties of a system since they get changed with a change in the amount of substance in the system. Properties like temperature, pressure, density, specific gravity, refractive index and specific heat capacity are called the intensive properties of the system. These properties do not change with a change in the amount of substance.
The physical quantity entropy is a measurable quantity and describes the ability of the system to do work. Entropy is often associated with disorder and the second law of thermodynamics is sometimes cast as a statement that the disorder of a closed system always increases. Since entropy measure the degree of randomness or disorder, therefore entropy like internal energy is an extensive property
