Different chemical changes that occur in below scenes should be determined. Concept introduction: Changes can be classified as physical and chemical changes. Physical changes are such changes that allow change of state of matter only but not formation of new substances. Reversal of such changes is possible by physical methods. Chemical changes allow formation of new and different substances from original substances via chemical reactions. These cannot be reversed back to original state by any method.

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
