Thermodyanamic System

What is a thermodynamic system?

• A thermodynamic system is an area in space upon which the study is concentrated.

• Everything outside the system is called surrounding.

• A boundary separates a system from the surrounding.

• There are three types of thermodynamic systems.

1.Open system

2.Closed system

3.Isolated system

• 

1. Open System :

• It is a type of system in which both mass and heat can cross the boundary.

     Example:

          A cup of hot coffee is a perfect example of an open system since both heat and mass can cross-system boundaries.

         Boiling water in an open system.

    2.  Closed System :

         It is a type of system in which only heat can cross the boundary.

       Example:

       A pot of boiling water with a lid over it is a perfect example of a closed system since only heat can cross the system's boundary.

    3. Isolated System:

It is a type of system in which neither heat nor mass can cross the boundary.

        Example:

        Hot water in thermos flask Is a perfect example of an isolated system since neither heat nor mass can cross-system boundary.
