b. A volume of air with a temperature of 68F and a vapor pressure of 10 mb mixes with a volume of air of temperature 86F and vapor pressure 30 mb. Does a cloud form? Explain your answer. c. You exhale on a day when the air temperature is 40F and the vapor pressure is about 9 mb. Do you see your breath? Explain your answer. What about on a day when the air temperature is 40F and the vapor pressure is 4 mb? Again, explain your answer. d. Assume that the water-air interface over a hot tub has a temperature of 104F and a vapor pressure of 70 mb. The environmental air (the air above the water-air interface) at this time has a temperature of 60F and a vapor pressure of 10 mb. Does steam fog form above the hot tub? Explain your answer. 80 70 60- 50 Vapor Pressure (mb) NW 20 10 40- 30- Equilibrium Vapor Pressure Curve 4. -40 -20 0 20 40 60 60 Temperature (F) 80 00 100 b.
