A very thin layer of oil floats on top of water. A drop of dye is placed at the center of the oil. The dye diffuses through the oil in all directions equally with a diffusion constant D0. Since the layer of oil is thin, we can assume the diffusion is two-dimensional. After a time T0 has passed, the dye has diffused a distance of 5 mm. If the dye had a diffusion constant of D0/3 what distance would the dye have diffused after a time T0/4? Give your answer in units of mm. (Round your answer to two decimal places.)

Balloons shrink because gas diffuses out of them. The rate of diffusion is faster for smaller particles and for particles of higher speed. Diffusion is also faster when there is a large difference in concentration between two sides of a membrane. Given these facts, explain why an air-filled balloon lasts longer than a helium balloon.arrow_forward
