Chemical change: when substances combine to form a new substance examples: burning wood, souring milk digesting food, baking cookies.
Physical Property: Characteristics that doesn't have to do with chemical changes. examples of physical property: color,texture, melting point, conductivity, and desity.
Chemical Property: reactions that are observed when a chemical change occurs. Examples: toxicity, burning, rusting, cooking, and rotting.
