Macroscopic Vs MicroscopicWhen a sy

Macroscopic Vs Microscopic
When a system has been chosen, the next step is to describe it in terms of quantities related to the behaviour of the system or its interactions with the surrounding or both. Two points of view may be adopted: macroscopic or microscopic,
Microscopic approach considers the behaviour of every molecule by using statistical methods. In Macroscopic approach we are concerned with the gross or average effects of many molecules' infractions. These effects, such as pressure and temperature, can be perceived by our senses and can be measured with instruments. This approach greatly reduces the complexity of the problem and we use this approach in this course. This is known as "Classical Thermodynamics".
