Question
Chapter 14, Problem 13Q
To determine
Why the wet sand is cooler to walk on than dry sand.
Expert Solution & Answer
Answer to Problem 13Q
Solution:
Evaporation of water causes cooling.
Explanation of Solution
The water trapped between the sand particles in case of wet sand starts evaporating when sunlight falls on it. We know that evaporation causes cooling. Hence, the wet sand is cooler to walk on. In case of dry sand, the particles become so hot that it becomes to walk on the dry sand beach.
