Background: Matter can undergo physical and chemical changes. In a physical change, matter changes its appearance physical properties but not its composition. Examples of physical changes include changes of state between solid, liquid, and gas phases , making mixtures, and changing size or shape. On the other hand, in a chemical change, matter does change its composition new substances are made. For example, the statue of liberty, which is covered with copper, turned green upon exposure to air because the copper reacts with the gases in the air to form new compounds. For each, describe the initial appearance and observation of the reaction during and after. Station Initial Observations Type of Change - Evidence to back Appearance of during and after physical or up the type of component s reaction chemical?
