Jason fills a glass container completely with water and screws the lid on tightly. He places the container in a freezer. Which will most likely result?*

• The container will prevent the water from freezing.

• The water will freeze and take up less space in the container.

• The water in the container will expand when it freezes and cause the container to crack.

• The container will absorb heat from the water, causing it to crack.

One morning, a student notices that the grass in the area is wet, although it had not rained during the night. What could have caused the grass to be wet?

• During the night, water had evaporated from the trees in the area.

• The air above the ground became warmer during the night and causes precipitation.

• When the air cooled above ground during the night, water vapor condensed on the grass.

• The grass soaked up water from the ground during the night.

Stirring a cup of hot tea causes a metal spoon to get warm. Which statement best explains why the spoon gets warm?

• Heat energy transfers from the metal spoon to the hot liquid.

• Heat energy transfers from the hot tea to the spoon.

• Heat energy transfers from the air to the hot liquid, and then to the spoon.

• Heat energy transfers from the hot liquid to the cup, and then to the spoon.

Which material is best used to keep cold drinks from getting warm too quickly?

• Glass, because it is a good conductor of heat

• Foam, because it is a poor conductor of heat

• Metal, because it radiates heat

• Paper, because it conducts heat

How does the energy from the sun influence the water cycle?

• By trapping water particles in clouds

• By turning liquid water into water vapor

• By causing water to precipitate

• By creating winds in the atmosphere
