Using the value of d, the collision diameter for argon of 362pm, calculate (a) the mean free path, (b) the average number of collisions a molecule experiences per second, and (c) the average number of collisions per cubic meter per second for the molecules of argon at 0 degree Celsius and 1 bar of pressure. (d) what values would be obtained at 1000 degree celsius and 1 bar? (e) At 0 degree celsius and 100 bar?
