What is system in thermodynamics and classification, explain with defination and exams

Question

Accepted Answer

A system in thermodynamics refers to a specific region or object under observation.

A system can be classified as open, closed, or isolated based on the exchange of matter and energy with the surroundings.
An open system allows both matter and energy to be exchanged with the surroundings, while a closed system only allows energy exchange.
An isolated system does not allow any exchange of matter or energy with the surroundings.
Examples of systems include a piston-cylinder, a refrigerator, and a car engine.
The classification of a system is important in determining the thermodynamic properties and behavior of the system.
