The correct answer is E. Evaporation of rubbing alcohol. A chemical reaction is a process that involves the breaking or formation of chemical bonds between atoms or molecules, resulting in the creation of one or more new substances with different properties. In the case of evaporation of rubbing alcohol, the liquid alcohol molecules are transformed into a gas state through the breaking of intermolecular forces between them
