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.
