Physical transformations are changes in the state or appearance of matter without altering its chemical composition, like melting ice or breaking glass. Chemical transformations involve changes in the chemical structure of substances, resulting in the formation of new substances, like rusting iron or burning wood. Learning about physical and chemical transformations helps us distinguish between these two types of changes. The Transformations Quiz for Grade 7 helps you test your knowledge about the conditions that cause these transformations and their importance in nature and industry. Answer these 10 questions to check your knowledge about physical and chemical transformations.
