Evaporation of a puddle of water has to be labelled as either a physical change or a chemical reaction . Concept Introduction: Physical change: A change in which no new substances are formed is said to be physical change. It affects the chemical substance but not its composition. Chemical reaction: It is a process that involves rearrangement of the molecular or ionic structure of a substance. In this, one or more chemicals reacts and forms other chemical compounds.
