Interactions Between Energy and Matter

When the sun warms water, which resulting process occurs?

• Precipitation

• Runoff

• Evaporation

• Condensation

Students observed a piece of iron change from shiny to rusty. What caused this change?

• A chemical reaction

• A heat reaction

• A cold reaction

• A physical reaction

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.

If a car is moving backward along a road, can its speed be measured?

• Yes, it can, because the car does not have friction acting on it.

• Yes, it can, because the car travels a distance in a certain amount of time.

• No, it cannot, because speed can only be measured if the car is moving forward.

• No, it cannot, because the distance traveled backward by a car cannot be measured.

Scientists discover an asteroid that is moving through space. What information is needed to determine the average speed of the asteroid?

• the mass and size of the asteroid

• the distance the asteroid is from Earth

• the direction the asteroid is moving and its distance from Earth

• how far the asteroid has moved in 24 hours

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 caused 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.

Two liquids are poured together, and a solid substance forms with no liquid remaining. Liquid 1 has a mass of 200 grams, and liquid 2 has a mass of 100 grams. What would be the total mass of the solid substance formed?

• 100 grams

• 150 grams

• 250 grams

• 300 grams

Which is the best example of a new substance forming?

• lighting a match

• cutting a piece of paper

• popping a balloon

• hitting a nail with a hammer

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

How do plants return water back into the environment?

• by evaporation

• by condensation

• by runoff

• by transpiration
