a) The average free path of the molecules in a gas is 10-⁴ cm, and the number of collisions of each molecule with the others is given as 2x10⁹ s-¹. Calculate the average velocity and diffusion coefficient of the molecules.
b) If the pressure of CO2 gas at 20˚C with a Joule-Thomon coefficient of 1.30 K/atm is reduced from 15 atm to 2 atm by Joule-Thomon expansion, what will be the final temperature?
