Physical And Chemical Changes Interactive Notebook Middle School Class 7 science chapter 6 physical and chemical changes textbook exercise questions and answers. question 1. classify the changes involved in the following processes as physical or chemical changes: a. photosynthesis. b. dissolving sugar in water. c. burning of coal. Chemical changes happen when something new is made, and the original stuff changes into something else. here are some examples: : when you bake a pie, the ingredients change because of the heat. the sugars and proteins transform, making a new pie with different properties. this is a chemical change. : when wood burns, it turns into ash and smoke. Changes in matter: physical vs. chemical changes. Figure 3.5.1 3.5. 1: ice melting is a physical change. when liquid water (h2o) freezes into a solid state (ice), it appears changed; however, this change is only physical as the composition of the constituent molecules is the same: 11.19% hydrogen and 88.81% oxygen by mass.
