question 1

identify the following as either chemical or physical

melting crayons

physical change

physical property

chemical property

chemical change

Explanation:

Melting crayons is a physical change. A physical change is a change in which the form or appearance of a substance changes, but its chemical composition remains the same. When crayons melt, they change from a solid to a liquid state. However, the chemical makeup of the wax in the crayons does not change. There is no new substance formed. A physical property is a characteristic of a substance that can be observed or measured without changing the substance's chemical composition (e.g., color, density). A chemical property is a characteristic of a substance that describes its ability to undergo a chemical change (e.g., flammability). A chemical change is a change in which one or more new substances are formed. Since melting crayons does not form new substances, it is not a chemical change or a chemical property. And it is a change (not just a property), so it is a physical change.

Answer:

physical change
