WebLet me just take this result, actually, and just put it in a new window so we can get a clean result. And look at what I get. I get that the pressure times the volume, if I multiply both sides by V, pressure times volume equals the number of gas molecules times m times the average squared x velocity in the gas. So this is pretty cool. alim calendarios
