True or False. When steam is no longer visible it becomes air.

• True

• False

Answer explanation

When water vapor condenses in the air it is visible as tiny water droplets.

The water in an open container seems to disappear after being left out. What actually happened to the water.

• It was absorbed by the container

• It changed into oxygen in the air.

• it evaporated; changing from a liquid to a gas.

• It disappears into nowhere

Answer explanation

Water in an open container evaporates, changing from a liquid to a gas.

Choose the statement that BEST describes the difference between ice and liquid water.

• Ice molecules are colder than water molecules.

• Ice molecules have less kinetic energy than water molecules

• Ice molecules have more kinetic energy than water molecules

• Ice molecules are warmers than water molecules

Answer explanation

Ice molecules have less kinetic energy than water molecules.

There is no such thing as "COLDNESS", just having less thermal energy

Which statement best describes the condensation on the glass?

• Condensation is when air turns into a liquid.

• Condensation is water vapor in the air that cools enough to become a liquid.

• Condensation is when liquids cool enough to turn into solids.

• Condensation is when liquid molecules gain enough energy to become a gas

Answer explanation

Condensation is water vapor in the air that cools enough to become a liquid.

How does the condensation on the window form?

• Condensation on the outside of the window is water that seeped (or sweated) through the window.

• Condensation of water vapor happens when the water vapor in air comes in contact with a cool surface.

• Condensation on the window appears when the window starts to melt.

• None of these.

Answer explanation

Condensation of water vapor happens when the water vapor in air comes in contact with a cool surface.

Why does matter take up more space when it's heated (thermal expansion)?

• Expansion of matter is due to the expansion of the particles rather than increased space between the particles.

• Matter expands when heated because the molecules are vibrating more quickly, and increasing the space between atoms or molecules.

• Matter takes up more space because the particles get bigger AND the space between them increases

• None of these

Answer explanation

The particles don't change size.

When more heat is added. The space between the particles increases.

When heat is lost the space between the particles decreases.

Which statement BEST describes the water cycle.

• The water cycle involves how oxygen moves through the atmosphere

• The water cycle involves only the storage and release of water.

• The water cycle involves freezing and melting of water.

• The water cycle involves evaporation of liquid water, condensation of water vapor, and precipitation (rain, sleet, hail, or snow).

Answer explanation

BEST ANSWER: The water cycle involves evaporation of liquid water, condensation of water vapor, and precipitation (rain, sleet, hail, or snow).

True or False. Water only gets evaporated from the ocean or lakes.

• True

• False

Answer explanation

Water can evaporate from plants, animals, puddles, and the ground in addition to bodies of water.
