CBSEENPH11026206

When you make ice cubes, the entropy of water

  • does not change

  • increases

  • decreases

  • may either increase or decrease depeding on the process used

Solution

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.
