Graham's apparatus
Graham's apparatus is a setup used to study how gases diffuse or mix over time. It typically involves two connected glass chambers separated by a thin, flexible membrane or barrier. When a difference in gas concentration or pressure exists, the gases move through or around the barrier, allowing scientists to observe the rate and behavior of diffusion. This experiment helps illustrate fundamental principles of gas behavior, such as how gases tend to spread out and mix, and can be used to calculate diffusion rates under different conditions.
