When you make ice cubes, the entropy of water
does not change
increases
decreases
may either increase or decrease depeding on the process used
C.
decreases
The entropy function gives us a numerical measure of the irreversibility of a given process, ie, it is a measure of disorder of a system. During formation of ice cubes orderedness increases, ie, disorderness decreases, hence entropy decreases.
