Definitions [2]
Define the term degrees of freedom.
The minimum number of independent coordinates needed to specify the position and configuration of a thermo-dynamical system in space is called the degree of freedom of the system.
Define mean free path and write down its expression.
The average distance travelled by the molecule between collisions is called mean free path (λ).
λ = `"kT"/(sqrt(2)π"d"^2"p")`
