Unformatted text preview: find that the outside temperature is 30°C. Answer the following questions: 1. What is the dewpoint temperature of the air? 5°C 2. What is the saturation vapor pressure of the air? 42.4 mb 3. Estimate the vapor pressure in the atmosphere. SVP at 5°C (dew point) is VP = 8.7 mb 4. Estimate the relative humidity of the air. 8.7/42.4 * 100 = 20.5% 5. Why did moisture condense on the outside of the cup? The air outside of the cup cooled to the dewpoint temperature and the atmosphere reached its maximum capacity. The vapor pressure passed its SVP and condensation occurred....
