Hence, the given statements are classified as follows.
(a) All matter is made of tiny, indestructible particles called atoms - Theory
(b) When iron rusts in a closed container, the mass of the container and its contents does not change - Observation
(c) In chemical reactions, matter is neither created nor destroyed - Law
(d) When a match burns, heat is evolve - Observation
