Taking a gas to be ideal and confined to a rigid metal box, findan expression for how quickly the mean free path of said gaschanges if the temperature is dropping cubically with time(​T​=​T​0- At^3) If the initial pressure of the gas is 105 Pa, theintermolecular radius is 2 Ångström, and the initial temperatureis 325 K and drops 1 K in the first second, what is the rate ofchange of the mean free path with respect to time after 6seconds?
