Question

1. students performed an investigation on how aluminum cans taken to a recycle center were able to be reused. they found out an aluminum can undergoes which type of change? a physical change because the material remains the same a chemical change because new metal is formed a physical change because the can is heated a chemical change because an old can is changed into a new can

Explanation:

In a physical change, the substance's chemical composition remains the same. When an aluminum can is recycled, it is melted and reformed into a new can, but it is still aluminum. No new substances are formed chemically. In a chemical change, new substances with different chemical properties are formed. Since the aluminum in the can remains aluminum throughout the recycling process and only its physical form (shape, etc.) changes, it is a physical change.

Answer:

B. a physical change because the material remains the same
