Answer

Brief Explanations:

A chemical change occurs when a substance is transformed into a different substance. Heating copper(II) sulfate pentahydrate leads to gas release and color - change, indicating a new substance formation. Physical changes only affect physical properties like state without changing the substance's identity. Temperature change alone doesn't define a chemical change.

Answer:

chemical change because gas was released along with a color change, which indicated that the copper(II) sulfate pentahydrate was transformed into a different substance
