If we start from a gas below a critical point and decrease its temperature at a constant pressure. It is known that, being careful, one can prepare a supersaturated vapour and that it's imperfections like droplets, dust, etc that become a core on which liquid starts to condensate. From your description the reason for that seems to be that the probability of multiple collisions needed to form a few bonded molecules is very low. Is my understanding correct? | |
