The strength of interaction between molecules depends on the distance between them and can cause a deviation in the position of the molecules, even if they are far from “contact” with each other. This deviation will depend on the duration of the forces and on the relative speed of the molecules. a) Can you expect that the mean free path will depend on temperature, even if the density of the gas remains constant? b) If this is so, can we expect l to increase or decrease with temperature? c) How will this dependence enter into equality: ####
