Whether the dew condensing on a leaf can be reversed by changing the temperature or not is to be determined. Concept introduction: The change that takes place only in state or appearance and not in the composition is known as physical change. The atoms or the molecules of a substance do not change their identity when a substance undergoes a physical change. The substance remains the same before and after the change. Physical change brings change in physical properties only. For example, the melting of ice is a physical change. Ice ( water ) → liquid ( water ) The physical change can be represented as follows: The change that takes place in the composition is known as chemical change. The atoms or the molecules of the substance rearrange and transformed into a new substance. A chemical change can change physical as well as chemical properties of a substance. For example, the burning of paper is a chemical change. Paper ( cellulose ) → ash ( carbon ) The representation of chemical change is as follows:
