Melting of ice is a physical change or chemical change.
Hint: Energy changes are always accompanied by a specific chemical or physical change.Many changes occur in a natural environment, such as water evaporation, condensation, and rainfall, to name a few. All of these modifications are accompanied by a change in state.
Complete answer: Melting ice is a physical change since it simply involves a change in the physical state of water, from ice to water in the liquid state. Furthermore, no new chemical substances are created throughout the process, and the transformation is reversible. Simply freezing water will turn it back into ice. As a result, melting of ice is a physical change.. The arrangement of molecules is altered during the physical change, resulting in a change in state. There are no new products created, and the molecular makeup remains unchanged. The molecular composition of ice and water, for example, is unaffected. When a physical change occurs, no energy changes occur. The amount of energy required to bring about a physical change is the same as the amount of energy required to reverse it. The energy level does not change. The changes are reversible and only last for a short time. If the cause of the change is eliminated, the reaction will be reversed. The mass of the substance does not change throughout the physical change. Only energy is added or removed in a physical change; mass is not involved. A chemical change occurs when the molecular composition is totally transformed and a new product is created. A new product is formed as a result of chemical modifications. Chemical transformations are irreversible and permanent. Chemical change cannot be reversed by changing or altering the experimental changes. The mass of the substance is altered during a chemical change. Either the mass is added or removed. During a chemical change, the energy changes occur.
Note: In a chemical change, when energy is released, the reaction is called an exothermic reaction; when energy is absorbed, it is called an endothermic reaction. There is an energy difference in the breaking of old bonds in reactants and the formation of new bonds in products.
