Chemical Change
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.
Ms. Brown asked her students to combine some regular cow's milk with white vinegar. Each group mixed 1 cup of warm milk with 4 tablespoons of vinegar in a glass measuring cup. After stirring the mixture, the students poured the liquids through a strainer into another beaker. The picture above shows the results of mixing warm milk with vinegar. What type of change is this? Explain.
It is a chemical change because two liquids mixed together something new and different.
It is a physical change because it is a mixture of two liquids.
It is a chemical change because there was a change in temperature of the milk.
It is a physical change because you can separate the parts with a strainer.
