Physics Question on Thermodynamics

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

Answer

decreases

Explanation

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 ordered ness increases, i.e., disorder ness decreases, hence entropy decreases.
