Understanding Physical and Chemical Changes: Final Exam Review

In today's review, we will explore the concepts of physical and chemical changes. You will differentiate between the two types of changes, answering questions based on examples provided. A physical change does not alter the substance's composition, while a chemical change results in the formation of a new substance. You are encouraged to refer to your textbook or notebook as needed to complete the exercises. We will examine specific examples—shredding paper, burning paper, melting ice, freezing water, water evaporating, and rusting metal—to categorize these changes correctly.
