Question
Chapter 18, Problem 20A
(a)
To determine
Out of the elephant or mouse, the one which has more skin.
Expert Solution & Answer
Explanation of Solution
Introduction:
For larger animals, surface area is less compared with its weight. Smaller animals have large surface area for smaller weight.
The size of an elephant is larger than mouse. The surface area of elephant is larger than the surface area of mouse.
Conclusion:
Elephant has more skin than the mouse.
