Terminology of Thermodynamics

The important parts of the study of thermodynamics are a few terms and definitions, which must be understood clearly, and these are as follows:

1. System, boundary and surroundings: A thermodynamic system may be defined as any specified portion of matter in the universe which is under study. A system may consist of one or more substances.

The rest of the universe which might be in a position to exchange energy and matter with the system is called the surroundings.

Thus, the system is separated from the surroundings by a boundary which may be real or imaginary.

In experimental work, a specific amount of one or more substances constitutes the system. Thus 200 g of water contained in a beaker constitutes the thermodynamic system. The beaker and the air in contact are the surroundings.
