Answer: See below
Explanation:
p-(p+20) = 4(p-5) + 3p
p-p-20 = 4p - 20 + 3p
-20 = 7p -20
40 = 7p
40/7 = p
The answer to the question is the total surface area increases and chemical composition changes. Consider the breakdown of rock into smaller pieces, these fragments vary from huge rocks to smaller sizes. As they are so crushed and broken they tend to occupy much of the surface area than when its just a huge rock.
