Answer 1

A positive change in Entropy means that there is more disorder in the system. More disorder is indicated, in this case, as the particles occupying more of the containers than they do initially. This is indicated in the first example and second example. In the last example the Entropy decreased as the particles occupy less container that they do initially. In the third example there is a decrease in Entropy as less of the particles are distributed in the other containers than initially.
