Thus , evaporation of water is not a chemical change but merely a Physical process. Therefore, it is an example of a physical change. For example Gold is still Gold even if you melt it down into a liquid, Chemically changing something alters the substance completely. Does mass change during a physical change? Do changing pad covers fit all changing pads? When water evaporates, it undergoes a physical change. Explanation: It is a physical change because it is going from the liquid phase to the gas phase. Acid rain damaging a marble statue is a physical change. Explain your answer. What cars have the most expensive catalytic converters? Sand being washed out to sea from the beach is a chemical change.
