参考答案:
On a hot humid day, there is little evaporation
from a human due to perspiration, because the air is already saturated with
water vapor. Since perspiration is a
major cooling mechanism, when it is restricted, humans will feel more
uncomfortable. On a hot dry day, water
molecules more easily evaporate into the air (taking their kinetic energy with
them) and the body is cooled.
