Question

Quizplus · Accepted Answer

Evaporation of river water is a physical change because it does not involve a chemical reaction, only a change in state from liquid to gas. Rusting of an iron statue, burning of paper, and curdling of milk are all examples of chemical changes because they involve a transformation of one substance into another through a chemical reaction.
