    When you make ice cubes, the 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, ie, it is a measure of disorder of a system. During formation of ice cubes orderedness increases, ie, disorderness decreases, hence entropy decreases.
