Closed, open and isolated system-Thermodynamics system:
Sol: In thermodynamics the system can be defined as the quantity of matter or region in space upon which attention is concentrated for sake of analysis. These systems are referred as thermodynamics system.
It is bounded by arbitrary surface called as boundary. The boundary can be real or imaginary, can be at rest or in motion and may can its size or shape.
Everything outside the arbitrary selected boundaries of the system is called as environment or surrounding.
Figure--The system The union of system and surrounding is altogether termed as universe. Universe = System + Surrounding
Types of system
The analysis of thermodynamic processes comprises of study of the transfer of mass and energy across the boundaries of system. On the basis system can be mainly classified into three parts.
(i) Open system (ii) Closed System (iii) Isolated system
