Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...
