Are there other ways to increase the entropy of the universe than dispersing energy as heat? For example, say I have a jar filled with 100 white marbles, and I shake it up. I have increased the entropy of the universe by dispersing heat energy from a high temperature (burning the fuel in my body) to a low temperature (heating up the marbles a little). Now suppose I have an identical jar with 50 red marbles neatly packed on top of 50 yellow marbles, and I shake the jar the same way I did the other one. Is the increase in entropy the same as with the white marbles? Or is it more because I have mixed up two different color marbles, in addition to heating them up?
