The cloud chamber is filled with isopropyl alcohol vapor. The chamber is warm at the top, extremely cold at the bottom. At a certain height, the temperature is low enough that the vapor will condense to make droplets, a cloud, if there is something for a droplet to form on, a nucleation site. This can be a dust particle, or the ions produced by ionizing radiation traversing the chamber. This is the source of the trails of cloud that appear in the chamber; these are the tracks of high-energy charged particles. If you compared the track of an alpha particle and a beta particle, the track of the alpha particle would be , but the track of the beta particle would be .

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
