If cream, sugar, and flavorings are mixed and frozen to make ice cream is a physical change or a chemical reaction . Concept introduction: Physical change is defined as that change in which the chemical composition of the substance does not change. In physical change one form of a substance is changed to another form, no new product is formed. Examples of physical change are condensation, melting and freezing. A chemical change is defined as that change in which the chemical composition of the substance changes. In a chemical reaction, the formation of a new product takes place. Examples of a chemical reaction are rusting of iron and formation of a precipitate.
