Among the given processes, the processes that undergo a physical change are to be determined. Concept introduction: A physical change is a change where the identity of matter does not change, but the state of matter changes. A chemical change is a change where the identity of matter changes and leads to the formation of new substances.

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).
