Reversible physical change example

On the other hand, the physical reaction causes a change in the physical properties of the reactant, e.g., color, shape, and size, etc. A chemical reaction is a type of irreversible or unchangeable reaction. Conversely, the physical reaction is a type of reversible reaction The water remains water in both cases hence this is a reversible change. (ii) Lightening of an electric bulb: During this change, electricity is passed through the filament which becomes white hot and glows, but when switch is off, the filament returns to its original shape and condition, hence it is totally reversible When a physical change occurs the chemical composition of the substance doesn't change. Some examples of physical changes are melting, freezing, vaporization, and condensation. Physical changes can be reversed, usually by heating or cooling the substance, without any chemical bonds being broken or formed Some curricula talk of physical changes as being reversible, and chemical change being irreversible. Examples of irreversible chemical changes would be the burning of wood, or a candle, or the reaction of vinegar and baking soda to form carbon dioxide, water and a salt. However Also, a change in which reactants can be recovered from the products or vice versa is known as a reversible change. For example, melting tin and then cooling it into a mold is a physical change as no new compound is forming. Also, it is a reversible change because by heating the tin we can melt is again. Thus, we can conclude that melting tin.
