Your head feels colder under an air-conditioning vent when your hair is wet than when it is dry. Why?

Wet atmospheric air at 100 percent relative humidity contains saturated water vapor and, by Dalton’s law of partial pressures,

$$P_{atm} = P_{dry air} + P_{water vapor}$$

Suppose this wet atmosphere is at 40°C and 1 atm. Calculate the density of this 100 percent humid air, and compare it with the density of dry air at the same conditions.

Compare the molecular structures of cotton and polypropylene, the two major components of thermal underwear. One of these gets wet easily and holds the water in contact with the skin. The other one does not get wet, but wicks the water away from the skin and feels relatively dry to the touch. Explain the difference in how these two fabrics respond to moisture.

Predicting Consequences Describe two ways that a small butte would change if it was in a wet climate, rather than a dry climate.
