When a substance is produced, it can be either a chemical or physical change, depending on the nature of the process. A chemical change results in the formation of new substances with different chemical properties, like when iron rusts. In contrast, a physical change involves alterations in the state or appearance of a substance without changing its chemical composition, such as ice melting into water. Therefore, the type of change depends on whether new substances are created.

Is the process of evaporating water from seawater a physical property?
No, the process of evaporating water from seawater is a physical change, not a physical property. Physical properties are characteristics of a substance that can be observed without changing the substance itself, whereas physical changes involve a change in the state or appearance of a substance without altering its chemical composition.

Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
