"WebA thermodynamic system means the quantity of fixed matter with identity. The composition of the matter inside any system may be the same or maybe changed through various reactions. It contains matter and device (s) on a control surface. Its boundaries may be closed, may be open, may be movable, may be stationary, may be real or imaginary too.

Chapter 5 The First Law for open systems Understanding Thermodynamics …

A system is enclosed by walls that bound it and connect it to its surroundings. Often a wall restricts passage across it by some form of matter or energy, making the connection indirect. Sometimes a wall is no more than an imaginary two-dimensional closed surface through which the connection to the surroundings is direct. A wall can be fixed (e.g. a constant volume reactor) or moveable (e.g. a piston). For example, i… WebI teach undergraduate thermodynamics and I was quite ashamed that I couldn't explain to a student, the following.
