Debbie is learning about weather. She wonders how temperature affects the rate of evaporation. She conducts an experiment to find out by placing equal amounts of water in identical dishes. She places one dish near a sunny window and the other on a table in a windowless, air-conditioned room. In three days, she returns to check the dishes. What will she find?

• A. The two dishes contain the same amount of water.

• B. Both dishes contain more water than they did three days ago.

• C. The water in the dish in the windowless room has completely evaporated.

• D. The dish near the window contains less water than the dish in the windowless room.

A science class is conducting an experiment to learn about the water cycle. The students fill two cups with water and place them in sealed plastic bags, as shown below. They place one bag on the windowsill in the sunlight. They place the other bag in the shade. The next morning, they find water in the bottom of both bags. The bag in the shade has less water in the bottom than the bag in the windowsill.

• A. The warmer temperature caused more water to enter from the top of the bag.

• B. The warmer temperature caused more water to condense.

• C. The warmer temperature caused more water to evaporate into the air.

• D. The warmer temperature caused the water to leak through the cup into the bag.

In Florida, it rains more in the summer than it does the rest of the year. What is the most likely explanation for this?

• Evaporation does not take place in the summer, which allows rain to fall freely.

• Evaporation slows down in the summer, which causes water vapor to form fog.

• Evaporation speeds up in the summer, making more water vapor available to form rain.

• Evaporation speeds up in the summer, making less water vapor available to form clouds.

An area is getting a thunderstorm. There are thick thunderclouds. High in the atmosphere, strong winds are pushing drops of liquid water upward. The liquid water enters areas of the atmosphere that are cold enough to freeze the water. This weather will most likely cause __________ to form.

• hail

• rain

• sleet

• snow

Water Vapor Investigation

Students learning about water vapor have a hard time believing their teacher when he says that water is constantly evaporating and always in the air. The students want to conduct an investigation to answer the question, "How are we able to tell if there is water vapor in the air?"

Their teacher provides the students with cobalt chloride test paper, which is normally blue but turns pink when exposed to air with water vapor in it.

Which of the following results would allow the students to conclude that they can tell that there is water vapor in the air?

• test paper placed in air with water vapor is pink, and test paper placed in air without water vapor is blue

• test paper placed in air with water vapor is blue

• test paper placed in air without water vapor is blue

• test paper placed in a cup filled with water is pink, and test paper placed in a dry cup is blue

Mr. Barnes wants to know whether the amount of sleep that students get the night before a test affects how they do on the test. He conducts a survey of his class. He finds that students who slept for 9 hours the night before a test scored better, on average, than students who slept for 7 hours. What do the results of the survey suggest?

• Getting more than 9 hours of sleep does not affect a student's performance on a test.

• Students who get less than 7 hours of sleep do poorly in school.

• Getting over 7 hours of sleep might help a student do better on a test.

• The amount of sleep a student gets is the most important factor in school performance.
