Gas diffusion, 3 of 3. Gas diffusion is demonstrated using nitrogen dioxide (NO2) gas. Nitrogen dioxide is heavier (more dense) than air and has a characteristic brown colour. A jar filled with nitrogen dioxide is placed under an inverted glass (Photo 1). After 3.5 min the gas is seen diffusing into the volume between the glass and the jar (Photo 2). After 13.5 min the gas uniformly fills the whole volume under the glass (Photo 3). | |
