You might notice that the ice slowly seems to disappear, leaving only liquid water in the cup. Then the liquid water gradually disappears too, leaving an empty glass. What happened to all of the water? | chemistry Type/draw here. | This phenomenon shows a few important concepts in chemistry, which is the study of matter and how substances interact with each other. The water in the glass never actually disappeared or changed. Instead, it just changed forms. This means there were | several physical changes. The water was three different states of matter - solid, liquid, and gas. The water began as a solid in the form of ice. As energy from the sun's heat was added to the ice cube, it melted. states of matter | Type/draw here. | physical changes Type/draw here. a a\" a _ TA nad weil Pa ba ae a Chemical and Physical Changes Part 1 This means it changed from a solid to a liquid. Then, the liquid water in the glass gained even more energy and evaporated. It changed from a liquid to a gas. Here is the most important thing about physical changes. Physical changes only change the shape, size, or form of a substance. They do not change what it is. Throughout the entire process of melting and evaporation, the water had the exact same chemical composition. When matter changes identity rather than just form, we call this a chemical change. This involves breaking and forming new chemical bonds. These are the links between atoms in a substance that determine its identity. pid
