Description:
The cloud chamber makes it possible to view the tracks left by particles emitted by a radioactive source. The cloud chamber consists of a lower chamber into which an alcohol and dry ice mixture is placed, an upper glass chamber which is saturated by alcohol vapor by adding alcohol to a pad in the top, and a light to enhance visibility. Once the plate at the bottom of the observation chamber cools down, due top the alcohol-dry ice mixture in the bottom, the air near the plate becomes supersaturated with alcohol vapor. Now tracks will become visible as the particles cause the alcohol to condense. It is possible to distinguish between alpha and beta particles and gamma rays due to their different tracks.
