12.12 The Dynamical and Thermqdynamical State of a System
The dynamical state of a system consisting of a large number of components is determined by the total number of degrees of freedom specifying the positional and momentum co-ordinates of all the components. The thermodynamical state of a system is defined by its average property taken in bulk. It is defined by lesser number of co-ordinates such as pressure, volume and temperature.
A dynamical state with a particular distribution of velocities amongst the component parts of the system is called a macro state or a thermodynamic state. Now, one macro state can be realized in a large number of ways each of which is called a complexion. Thus suppose we have a system consisting of N parts, each ...
