1)
A) How many kilograms of water can be evaporated from a 1 m2 surface of water in a lake on a hot, clear summer day, if it is assumed that the limiting factor is the Sun's heat of 1800 Js1m2 for an 8-hour day? Assume that the air and water temperatures remain constant at 40C.
B) What volume of air is needed to hold this much water vapor at 40C?
C) When the Sun sets, the air temperature drops to 20C. Assuming that the excess water vapor is precipitated as rain, calculate the weight of the rain.
D) Assuming that the excess water vapor is precipitated as rain, calculate the amount of heat released when the water condenses.
E) Calculate the vapor pressure of liquid water at 200C. Assume that the heat of vaporization does not change from its value at 100C.
