Question

Help I don't understand this question:

Use the second law of thermodynamics to analyze the scientific and economic feasibility of each of the following processes:
A) Extracting most mincerals dissolved in seawater.
B) Mining increasingly lower grade deposits of minerals
C) Using inexhaustible solar energy to mine minerals
D) Continuing to mine, use, and recycle minerals at increasing rates

Answer 1

C) Using inexhaustible solar energy to mine minerals

second law of thermodynamics deals with energy:
the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.
