How will you distinguish between intensive and extensive properties?

(i) Intensive properties: These are the properties which depend on only upon the nature of the substance and are independent of the amount of the substance present is the system. The common examples of these properties are temperature, pressure, refractive index, viscosity, density, surface tension, specific heat, freezing point, boiling point etc.

(ii) Extensive properties: These are the properties which depend on upon the quantity of the matter contained in the system. The common examples of these properties are mass, volume, heat capacity, internal energy, enthalpy, entropy, Gibb’s free energy etc.
