State giving reasons whether the entropy change for vaporisation of one mole of water will be more or less than entropy change per mole for fusion of ice.

Text Solution

AI Generated Solution

To determine whether the entropy change for the vaporization of one mole of water is more or less than the entropy change per mole for the fusion of ice, we can analyze the processes involved in both changes of state. ### Step-by-Step Solution: 1. **Understanding Entropy**: - Entropy (S) is a measure of the degree of randomness or disorder in a system. Higher entropy indicates a greater degree of disorder. 2. **States of Matter**: ...
