Question

explain mean free path...... urgent plz​

Answer 1

Explanation:

The mean free path or average distance between collisions for a gas molecule.

λ = 1 /( √2 π n² d)

• The mean free path could then be taken as the length of the path divided by the number of collisions.
• The mean free path is determined by the criterion that there is one molecule within the "collision tube" that is swept out by a molecular trajectory.
