Despite profuse sweating, a person feels stuffy and hot in a tropical forest at a relatively low air temperature (26–27°C). Why is profuse sweating not an effective method of heat transfer in this case?
- A. Air temperature reduces sweat evaporation
- B. High air humidity reduces radiation
- C. Air temperature increases sweat evaporation
- D. High air humidity increases sweat evaporation
- E. High air humidity reduces sweat evaporation
Hint
The cooling effect of sweat comes only from the evaporation of water from the skin, which depends on how much more water vapour the surrounding air can accept.
