Changes in States of Matter

What are the three main states of matter?

• solid, liquid, gas

• gas, liquid, crystal

• solid, liquid, plasma

• plasma, vapor, foam

What happens to water when it freezes?

• Water turns into steam when it freezes.

• Water evaporates completely when it freezes.

• Water contracts and becomes denser when it freezes.

• Water expands and forms ice when it freezes.

What is the process called when a solid turns into a liquid?

• Condensation

• Melting

• Freezing

• Sublimation

Can you name a gas that is present in the air?

• Helium

• Oxygen

• Nitrogen

• Carbon Dioxide

What is evaporation?

• Evaporation is the process of vapor turning into ice.

• Evaporation is the process of liquid turning into vapor.

• Evaporation is the process of gas turning into liquid.

• Evaporation is the process of solid turning into liquid.

What happens to ice when it melts?

• Ice becomes solid again after melting.

• Ice turns into steam when it melts.

• Ice turns into liquid water when it melts.

• Ice transforms into gas when it melts.

What is condensation?

• Condensation is the mixing of different gases in the atmosphere.

• Condensation is the transformation of water vapor into liquid water.

• Condensation is the evaporation of liquid water into vapor.

• Condensation is the process of freezing water into ice.

How does heating affect the state of matter?

• Heating can change the state of matter from solid to liquid, liquid to gas, or gas to plasma.

• Heating only affects gases.

• Heating has no effect on the state of matter.

• Heating can only change liquids to solids.

What is a common example of sublimation?

• Salt dissolving in water.

• Ice melting into water.

• Dry ice turning into carbon dioxide gas.

• Water boiling into steam.

Why do we see steam when water boils?

• Steam is caused by the water reaching a specific temperature.

• We see steam because water vapor condenses into tiny droplets in the air.

• Steam is the result of chemical reactions in the water.

• Steam is created when air is mixed with boiling water.
