Sweating cools the body efficiently because water has a high
- A. specific heat capacity
- B. latent heat of vaporisation
- C. surface tension
- D. density
Explanation
A large amount of energy is needed to break the hydrogen bonds holding liquid water together and convert it to vapour, and that energy is drawn from the skin, so a small volume of sweat removes a great deal of heat. High specific heat capacity is a different property, the one that lets a cell resist temperature change in the first place. Confusing the two is the usual error in this question.
