When sugar is dissolved in tea, the reaction is always accomplished by
-
positive change in entropy
- negative entropy change
- no entropy change
- a minimum entropy change
The correct answer is: A
Explanation
The dissolution of sugar in tea is accompanied by positive change in entropy. When there is a change in the state of a substance from solid to liquid, there is an increase in entropy. In general, if a substance changes its structure from a condensed state to a less condensed state, then we say there is an increase in entropy.
