Directions: Write the fraction then find the percentage. • 1. There are 8 units of water in the air. At its current temperature, the air can hold 10 units of water. What is the relative humidity? • 2. There are 24 units of water in the air. At its current temperature, the air can hold 25 units of water. What is the relative humidity? • 3. In question 2, the air was holding 24/25 units of water. What would happen if it got colder?

At its current temperature, the air can hold 25 units of water. What is the relative humidity? • 3. In question 2, the air was holding 24/25 units of water. What would happen if it got colder? = 24 25 100 96 96% = The drop in temperature would cause the air to hold less water and become saturated. At 24/24, it would precipitate.
