What happens when ice is heated?

• It becomes gas

• It becomes liquid

• It stays solid

• It freezes

What is the process called when liquid water turns into gas?

• Melting

• Evaporation

• Freezing

• Solidification

Which of the following is an example of solidification?

• Ice turning into water

• Water turning into steam

• Water freezing into ice

• Ice melting into water

What happens during condensation?

• Gas turns into liquid

• Liquid turns into gas

• Solid turns into liquid

• Liquid turns into solid

If you leave a cold drink outside on a warm day, what happens on the outside of the glass?

• The glass gets hotter

• The glass becomes dry

• Water droplets appear on the glass

• The glass breaks

Why does water boil when it is heated?

• It turns into solid

• It turns into gas

• It stays in liquid form

• It freezes

Imagine you have an ice cube. You place it in a warm room. What will happen to the ice cube over time, and why?

• The ice cube will freeze because it is cold.

• The ice cube will melt into water because it is heated by the warm air.

• The ice cube will stay the same because it is in a warm room.

• The ice cube will turn into gas.

If you place a cup of hot water outside on a cold day, what will happen to the water, and why?

• The water will evaporate because the sun is shining.

• The water will freeze because it is cold outside.

• The water will remain liquid because it is hot.

• The water will turn into a gas because it is heated.

If you put a cold glass on a warm surface, what do you think will happen to the water droplets on the outside of the glass, and why?

• The droplets will disappear because the glass is cold.

• The droplets will turn into gas because the surface is warm.

• The droplets will turn into liquid because the water vapor in the air cools and condenses on the glass.

• The droplets will freeze because the glass is cold.

Imagine a cycle where water is first heated to become gas, then cooled to become liquid, and finally frozen into solid. Can you explain how this cycle of changes in matter happens in nature, such as in the water cycle?

• Water evaporates into gas, then condenses into liquid, and finally freezes into solid ice when the temperature drops.

• Water evaporates into liquid, then freezes into gas, and finally turns into water vapor.

• Water freezes into gas, then evaporates into solid, and condenses into liquid.

• Water freezes into liquid, then evaporates into gas, and finally turns into steam.
