This is a chemical change, also known as a chemical reaction.
Chemistry is the scientific study of the composition of substances and their properties. It also deals with the ways in which these substances interact, combine, and change to form new substances.
These substances are called reactants.
"A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances" From This I gather that its a physical change as the cheese isn't changed into another substance, The cheese doesnt change, for example it doesnt taste or smell different, But its physical propertys do change it looks different

Chemistry is the scientific study of the composition of substances and their properties. It also deals with the ways in which these substances interact, combine, and change to form new substances.
A chemical reaction causes substances to combine in different ways to make other substances.
Its a chemical change, and the simplest is when two atoms combine to from a compound. When there is a single oxygen atom, it is called ozone, then two combine in an ionic bond, they are an oxygen molecule.
When substances combine and retain their own properties, the result is a mixture.
