How can a physical change generally be?

Answer and explanation

Correct answer: Often reversible

In a physical change, the chemical composition of a substance does not change; only its state, shape, or form may change. Therefore, many physical changes, such as melting and freezing, are reversible. Formation of a new substance is a feature of a chemical change, so option C is incorrect. Exam tip: if the original substance can usually be obtained again, the change is generally physical.
