Solution
The concept of entropy relates to the disorder or randomness of particles. In general, the entropy of substances increases from solid to liquid to gas. This is because particles are most ordered in a solid and most disordered in a gas.
Given the options:
A. O2(g) - This is a gas, so it would have a high entropy. B. H2O(s) - This is a solid, so it would have a low entropy. C. H2O(l) - This is a liquid, so it would have a moderate entropy. D. H2O(g) - This is a gas, so it would have a high entropy.
Therefore, out of the given options, H2O(s) or solid water (ice) would have the lowest entropy.
