What Happens When A Substance Undergoes A Physical Change. When a substance undergoes the physical change from one state to another or a transition of matter form one state to another: Physical changes affect a substance’s physical properties but do not alter its chemical structure.
An ice cube can melt into liquid water, and then the liquid water can be frozen back into an ice cube. Chemical changes, on the other hand, are not reversible: Chemistry matter physical and chemical changes.
