This programme is a general introduction to the kinetic theory of gases, making ext...ensive use of large-scale models of molecules. John Walters introduces the programme with a look at the gas equation PV = nrtT and the assumptions of kinetic theory. Keith Hodgkinson then shews us a mechanical analogue: elastically colliding pucks on an air table. He uses a "piston" to give us a fixed "volume" and shows that an increase in "T" leads to an increase in "V". He then shows us (electronically) the "ra
