This quiz will prepare you for the Water Vapor test.1. Ted filled up two different glasses, each with the same amount of water. One glass was wide, one glass was tall. He left them out for the same amount of time. More water in the wide glass evaporated than in the tall glass. Why?

[ ] The wide glass had more heat.

[ ] The wide glass had more surface area for the water to evaporate

[ ] The wide glass had less water to begin with

[ ] He did the experiment wrong.

2. Why does a hair dryer make hair dry faster?

[ ] The hair dryer runs on electricity.

[ ] There is more air movement and more heat.

[ ] Hair looks better when you use a hair dryer.

[ ] There is less water to evaporate.

3. Evaporation only happens when water is heated to high temperatures.

[ ] a. True

[ ] b. False

4. How are dew and frost similar?

[ ] They both happen only in the winter.

[ ] They are both types of water vapor.

[ ] They are both frozen water.

[ ] Dew is liquid, and frost is solid (ice).

[ ] Dew only happens on cold surfaces, frost can happen anywhere.

[ ] Frost only occurs in the morning, while dew happens anytime.

6. How can you turn liquid into water vapor faster?

[ ] decrease the amount of water, heat the water, transfer energy to the water (movement).

[ ] increase surface area of water, heat the water, transfer energy to the water (movement)

[ ] decrease surface area, heat the water, transfer energy to the water (movement)

[ ] the only way to do it is to add heat.

7. How does temperature affect the amount of water vapor in the air?

[ ] Temperature does not affect the amount of water vapor in the air.

[ ] Warm air holds less water vapor than cool air.

[ ] Warm air and cool air hold the same amount of water vapor.

[ ] Warm air holds more water vapor than cool air.
