... i. changes in amount of stuff ii. changes in physical state (gas to liquid, liquid to solid, , etc) but not to the molecules of the stuff ice = H2O (s), when melted becomes H2O (l) → physical state changes from s to l, but molecule stays H2O. This may become more clear after we discuss what molecule ...
