(a) If the partial pressure of water vapor is 8.05 torr, what is the dew point? (760 torr = 1 atm = 101, 325 Pa) (b) On a warm day when the air temperature is 35 °C and the dew point is 25 °C , what are the partial pressure of the water in the air and the relative humidity?
Suppose the relative humidity is 80% on a day when the temperature is 30.0ºC . (a) What will the relative humidity be if the air cools to 25.0ºC and the vapor density remains constant? (b) What is unreasonable about this result? (c)Which premise is responsible?
Suppose that air in the human lungs has a temperature of 37°C, and the partial pressure of water vapor has a value of 5.5 x 103 Pa. What is the relative humidity in the lungs? Consult the vapor pressure curve for water that accompanies this problem. Express your answer as a percentage with no units.
