Quizplus · Accepted Answer

All of the options are examples of physical changes as they involve a change in the physical state or appearance of the substance without any change in its chemical composition. Sugar dissolving in water or coffee being brewed both involve mixing of substances but no new compounds or elements are formed. Dry ice sublimes means it goes from a solid directly to a gas, and ice melting simply means changing from a solid to a liquid without any chemical reaction.
