Question
Which of the following has the lowest entropy?A.O2(g)B.H2O(s)C.H2O(l)D.H2O(g)SUBMITarrow_backPREVIOUS
Solution
The substance with the lowest entropy is B. H2O(s).
Entropy is a measure of disorder or randomness in a system. In general, the entropy of a substance increases from solid to liquid to gas. This is because the particles in a solid are more ordered and have less freedom to move around than in a liquid or gas.
Therefore, among the options given, solid water (H2O(s)) has the lowest entropy because its particles are in a more ordered state compared to liquid water (H2O(l)), water vapor (H2O(g)), or oxygen gas (O2(g)).
