What is created, destroyed, and changed?
This describes when two or more substances are combined and can be EASILY separated. You can still see all of the individual parts.
What is a mixture?
This is what happens to MOST objects when they are heated
What is expand?
This state of matter is an airlike substance that does not have a shape. It's atoms are VERY spread apart!
What is gas?
This is the type of property that describes the way an object behaves chemically. Examples include flammability, toxicity, radioactivity, etc.
What is chemical property?
How would the mass of bread change before or after baking?
What is the mass would stay the same?
This describes when two or more substances are combined that can NOT be easily separated. Most of the time, one substance is dissolved into another. You can not see the individual parts.
What is a solution?
What is contract?
This state of matter is a fluid-like substance that takes the shape of its container. The atoms in this state of matter are spread farther apart than the atoms of a solid.
What is gas?
This type of change can be reversed. It ONLY changes the object's appearance. Examples include cutting, folding, melting, evaporating, condensation, freezing, peeling, etc.

What is you could let the water evaporate until only the sugar is left?
What happens to water when it is heated and cooled?
What is water contracts when heated and expands when cooled?
