Matter can change: the changes can be physical or chemical. When a physical change happens, nothing new is formed. During a physical change, matter changes form; it can be crushed or torn or change state. When a chemical change occurs, something new is formed. The reactant or reactants change and become something new. For example, a piece of iron can rust. The rust is the new substance that is formed. It is called iron oxide. How can you tell if a chemical change has taken place? There are certain observations you can make:1. temperature change2. color change3. gas or bubbles produced4. an odor is created5. combining two liquids forms a solid called a precipitate.
