    When you make ice cubes, entropy of water:

    A)  does not change

    B)  increases

    C)   decreases

    D)   may either increase or decrease depending on the process used

    Correct Answer: C

    Solution :

    The entropy function gives us a numerical measure of the irreversibility of a given process \[i.e.,\] it is a measure of disorder of a system. During formation of ice cubes orderedness increases \[i.e.,\] disordemess decreases, hence entropy decreases.
