A dry-bulb thermometer is one of the thermometers in a psychrometer. Use the graph to answer questions 24 and 25.</p><p>Dry-Bulb Temperature (°F)</p><p>24. Interpreting Graphs What is the relationship between the temperature of the dry-bulb thermometer and relative humidity? a. As temperature decreases, relative humidity increases. b. As temperature increases, relative humidity increases. c. As temperature decreases, relative humidity decreases. 25. Applying Concepts The graph shows that when the dry-bulb thermometer is 42°F, the relative humidity is 100%. That is the temperature at which condensation begins. What will the water vapor form as it condenses? a. ice crystals b. water droplets c. snowflakes</p><p>© Pearson Education, Inc., publishing as Pearson Prentice Hall. All rights reserved. 11</p>
