Chapter 23, Problem 32A
At a picnic, why would wrapping a bottle in a wet cloth be a better method of cooling than placing the bottle in a bucket of cold water?
Expert Solution & Answer
To determine
The reason of getting more cooling a bottle than the bottle in a bucket of cold water .
Answer to Problem 32A
The reason is that the more evaporation from the wet cloth.
Explanation of Solution
As the wet cloth contains water in it . Due to evaporation the bottle getting cooling effect than the bottle in a bucket of cold water .
Conclusion:
The reason is that the more evaporation from the wet cloth.
