Explain degrees of freedom with examples. |
|
Answer» Solution :The degrees of freedom of the system are the minimum number of independent coordinates needed to SPECIFY the position and configuration of a thermo-dynamical system in space. Eg: (i)A PRACTICAL moving in space hasthree degrees of freedom. (ii) similarlypractice moving over a plan has two degrees of freedom. (iii) free practical moving along x-axis needs only one coordinate to specify it completely . So its degree of freedom is one. If we have a number of gas MOLECULES in the container , then the total number of degrees of freedom is F = 3N . But, if the system has kyon number of constraints ( restrictionsis motion ) then the degrees of freedom decreases and it is equal to f = 3N - q where N is the number of particles and q are constraints. |
