Define the term degrees of freedom.

1.	Define the term degrees of freedom.
Answer» Solution :The minimum number of independent coordinates needed to SPECIFY the position and connguration of a thermo-dynamical system in space is CALLED the DEGREE of freedom of the system. Example: 1. A free particle moving along x-axis needs only one COORDINATE to specify it completely. So its degree of freedom is one. 2. Similarly a particle moving over a plane has two degrees of freedom. 3. A particle moving in space has THREE degrees of freedom.
