Changes in Matter-

What can happen if the water in the picture loses its heat energy (cools)?

• It might freeze.

• It might boil.

• It might evaporate.

• It might condense.

When Joshua left his freezer pop on the bench it melted. What change state occured.

• liquid to gas

• gas to liquid

• liquid to solid

What can happen if heat energy is added to the water in the picture(heats up)?

• It might evaporate.

• It might freeze.

• It might melt.

• It might condense.

What change occurs during condensation?

• a gas cools and changes to liquid

• a liquid cools and changes to solid

• a liquid warms up and changes to gas

• a solid warms up and changes to liquid
