What is the Macroscopic and Microscopic approach of a thermodynamic system?

A thermodynamic system can be explained by taking into account by macroscopic and microscopic approach.In this article, I am going to explain about the Macroscopic and Microscopic approach of a thermodynamic system in a detailed manner.

What is the Macroscopic and Microscopic approach of a thermodynamic system was explained briefly.
What is the Macroscopic and Microscopic approach of a thermodynamic system?

Macroscopic approach:

  • No assumptions are to be made regarding structure of matter.
  • Very few parameters are required to specify the state of a system like Pressure&Volume,Volume&Temp,Temperature&Pressure.
  • They can be easily measured.
  • They can be felt by sense perceptions.

Microscopic approach:

  • Molecular theory of matter is assumed.
  • Many parameters are required to specify the state of a system.
  • For every molecule,3-position Coordinates & 3-velocity Coordinates are required.
  • For 1 mole of a gas,(6*6.023*10^23)coordinates are required.
  • They can’t  be easily measured.
  • They can’t be felt by sense perceptions.

Hence,though the approaches are different in explaining the thermodynamic system,but the conclusions are same.
