The standard molar entropy of `H_(2)O(l)` is `70 J K^(-1) "mol"^(-1)`.Will the standard molar entropy of `H_(2)O(s)` be more or less than `70 J K^(-1) "mol"^(-1)`?

To determine whether the standard molar entropy of `H₂O(s)` (solid water) is more or less than `70 J K^(-1) mol^(-1)` (the standard molar entropy of `H₂O(l)` or liquid water), we can follow these steps: ### Step 1: Understand the concept of entropy Entropy is a measure of the disorder or randomness in a system. The greater the disorder, the higher the entropy. In general, the states of matter can be ranked in terms of their entropy: gases have the highest entropy, followed by liquids, and then solids, which have the lowest entropy due to their ordered structure. **Hint:** Remember that entropy is related to the degree of disorder in a system. ### Step 2: Compare the states of water ...
