![]() The diffusion of these two miscible liquids is spontaneous, irreversible and entropy-producing, since the mixture has more microstates, and thus more entropy, than the pure components. Compared to its components it is very stable, and never reverts back of its own accord to the initial state of pure cream and black coffee. The narrative goes along these lines: When cream is added to coffee, diffusion and convection produces in the course of time a homogeneous-looking mixture. One of the devices that college lecturers like to employ when illustrating the concept of entropy is the one pictured above.
