1. A glass of water is left out in the air. The air temperature remains a constant temperature. As the water in the glass evaporates, what should happen to the temperature of the remaining water in the glass?

2. What is the relationship between the exposed surface area of a liquid and the rate of evaporation of the liquid?

3. The table below shows the vapor pressure of various liquids at a set condition. Which liquid would evaporate the fastest?

4. All of the particles of liquid at a given temperature have an identical amount of kinetic energy.

5. As the wind speed above a liquid surface increases, what would happen to the relative humidity of the air directly above the liquid?

6. A sling psychrometer is used to measure the relative humidity of air on two separate days. On day 1 the humidity is measured as 70%. On day 2 the humidity is 45%. Assuming all other factors were the same, which statement is correct?

7. A marathon course runs through hills, around lakes, and other areas. A person running the marathon is sweating. The sweating acts to cool the person off by evaporating the sweat off the skin. Table 2 shows the various sections of the course and the relative humidity values for each of the course sections.

Assuming all other factors are equal, in which section of the course would the person be cooled off the most due to sweating?

8. On which day would a puddle of water most quickly evaporate? Assume all other conditions are the same.
