Define- (i) Intensive property (ii) Extensive property. Give one example of each.

1 Answer

Answer :

Intensive property : It is defined as the property which is does not depend upon the mass of the system.

Or

Intensive properties are those whose values are independent of the mass possessed by the system.

Ex. Pressure, Temperature, Density, Specific volume, specific Enthalpy, etc.

Extensive property : It is defined as the property which depends upon the mass of the system.

Or

Extensive properties are those whose values are dependent of the mass possessed by the system, such as volume, enthalpy, and entropy.

Extensive properties are denoted by uppercase letters, such as volume (V), enthalpy (H) and entropy (S).

Per unit mass of extensive properties are called specific properties and denoted by lowercase letters. For example, specific volume v = V/m, specific enthalpy h = H/m and specific entropy s = S/m 

Ex. Total volume, Area, Enthalpy, Entropy etc.
