Diffusion data for example. Let's suppose we take McGinn's stance that, besides molecules, a gas might contain clusters of molecules called microdroplets, where we have defined "gas" to be any substance that obeys Boyle's/Mariotte's Law and Charles'/Guy-Lussac's Law, is not a bulk liquid or bulk solid, and consists of some kind of particles. Indeed, when those laws were established, the notion of molecules or atoms were not central or assumed. In fact, even in kinetic theory, the basic assumptions are wholly consistent with this notion of gas, as long as the microdroplets don't condense or aggregate; all that's needed is some sort of particle with long travel times between interactions and elastic collisions, which microdroplets are presumed to satisfy. (If they don't, then the microdroplet notion fails on not matching these gas laws.) Directly from kinetic theory, the rms speed of the particles is given by v=sqrt(3PV/Nm) or, taking a standard pressure and volume, v ~ 1/sqrt(m). This is pretty straightforward to use, and one can obtain that at STP, v for oxygen molecules should be 460 m/s, and because hydrogen molecules are 16 times lighter, v for hydrogen molecules will be 1840 m/s. This rms speed affects everything from the speed of sound (which is why the pitch in an organ pipe filled with helium is higher than the pitch in an organ pipe filled with air) to diffusion. The diffusion coefficient is directly proportional to the thermal speed. Thus, one can test McGinn's hypothesis of water microdroplets as particles in gas, simply by measuring the relative diffusion in a heterogeneous gas. For example, the molecular weight of water is 18 g/mol and the molecular weight of neon is 20 g/mol. A neon-water-vapor mix will then diffuse with both components at approximately the same diffusion rate. But if we suppose that the water is actually in microdroplet particles of, say, 16 molecules or so, then the diffusion rate for water would be 4 times smaller than that of neon. You could do the same diffusion test for argon-water-vapor or xenon-water-vapor mixes to determine the average weight of the water vapor particles. You could do the same with water vapor and toluene (mol. wt = 92 g/mol) or any other similar gaseous solvent of choice. McGinn might be deeply grieved to learn that relative diffusion measurements have already been done, but would recommend that he collect the data himself so that there is no doubt in his mind. -- Odd Bodkin --- maker of fine toys, tools, tables
