Question #241889
Why when a crystal of red fool colouring fell into a beaker of water, after a while all the water became red
Expert's answer
A crystal of red fool colouring slowly dissolves and its molecules diffuse through a beaker of water, demonstrating the driving force to increase the disorder of a system as it approaches equilibrium. This mixing process moves towards a state of equilibrium that we observe to be a uniform distribution of the dye molecules in the beaker.
