Title: Is diffusion affected by the shape of the liquid?
Post by: scientizscht on 30/11/2019 19:35:21
Hello!

Let's say we have a horizontal cylinder separated in half by a diaphragm. In the left compartment, there is a glucose solution of specific concentration and in the right compartment there is plain water.

When we remove the diaphragm, glucose will diffuse to the right at a specific rate e.g. 1cm/h.

Does the radius of the cylinder affect the rate of diffusion?

I would imagine that if the cylinder is very thin, at micron level, then the glucose will travel to the right much faster.

Is that true?

thanks!

No it won't.
