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?
O 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.
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.
O Hydrogen bonds rearrange at higher temperatures and form a lattice structure that requires energy. This energy
use lowers the heat in the body.
O Sweating is due to the high heat capacity of water. When sweating increases, heat is released and the body
temperature is lowered.
