Cutting bread. Boiling water is strictly a physical reaction for this reason. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. A Physical change affects only physical properties i.e. science. Slicing carrots. Often, physical changes can be undone, if energy is input. In the case of the alcohol evaporating, it's still alcohol in the end, but it's now a gas. answer explanation . Is water evaporating an example of a physical or chemical change?
