My question I have to answer is: A runner picks up pace on a warm day and starts sweating profusely. What property of water explains how sweating helps the runner continue running?
The following are four options I have to choose from to answer this question, and below that is the uncertain answer I chose.
A. Since water molecules are polar, they adhere to the surface of the skin, which allows cooling. The skin’s outer layer of dead cells enables the adhesion.
B. At elevated body temperature, the hydrogen bonds in water break, which allows water to escape as vapor. This causes heat loss in the body, which lowers body temperature.
C. Hydrogen bonds rearrange at higher temperatures and form a lattice structure that requires energy. This energy use lowers the heat in the body.
D. Sweating is due to the high heat capacity of water. When sweating increases, heat is released and the body temperature is lowered.
I chose (B), as (A) and (C) do not make sense and that (D) I think requires too much amount of time since water has a high heat capacity. Sweating, especially during running, is more immediate than (D). Would (B) be the correct answer?
