Predict whether the entropy increases or...

Predict whether the entropy increases or decreases for the following :
(i) 1 mol of liquid water changes to vapours.
(ii) when 1 mole of liquid water converts to ice.

Text Solution

AI Generated Solution

To predict whether the entropy increases or decreases for the given scenarios, we need to analyze the changes in the states of matter involved. ### Solution Steps: 1. **Understanding Entropy**: - Entropy (S) is a measure of disorder or randomness in a system. The greater the disorder, the higher the entropy. 2. **Analyzing the First Scenario**: ...
