Carefully pour a strong infusion of tea into the thick sugar solution on top, observe the change in the interface of liquids several times a day. Explain the observed phenomenon.

The line between sugar solution and strong tea will gradually become more and more blurred. This is due to the mixing of the tea molecules and the solution, the so-called. the phenomenon of diffusion, i.e. interpenetration of molecules of one substance between molecules of another. Eventually the molecules will mix and the solution will become a uniform color. Something in between the color of a strong tea and a sugar solution.
