Question

Thermodynamics deals with macroscopic properties. 

1. What is the difference between extensive and intensive properties? 

2. Classify the following properties into extensive and intensive.

 Pressure, Mass, Volume, Temperature, Density, Heat capacity, Viscosity, Surface tension, Internal • energy, Molar heat capacity, Refractive index, Enthalpy, Specific heat capacity

Answer 1

1. Extensive properties are those properties whose value depend on the quantity or size of matter present in the system. 

Intensive properties are those properties which do not dependent on the quantity or size of matter present in the system.

2. Extensive properties: Mass, Volume, Heat capacity, Internal energy, Enthalpy 

Intensive : Pressure, Temperature, Density, Viscosity, Surface tension, Molar heat capacity, Refractive index, Specific heat capacity.
