Question

(a)
Define mean free path of a gas. How
does mean free path of a gas vary with
temperature and pressure?​

Answer 1

Answer:

Radius of the molecule: As the radius of the molecule increases the space between the molecules decreases causing the number of collisions to increase, thus decreasing the mean free path. Pressure, temperature, and other physical factors also affect the density of the gas and thus affect the mean free path.
