As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged. Chemical changes, on the other ...
3 de may. de 2024 · A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
19 de oct. de 2023 · Matter is capable of undergoing changes, which are classified as either physical or chemical. Physical changes in matter are often reversible. For example, an ice cube can melt into liquid water, and then the liquid water can be refrozen into an ice cube. A chemical change is very different.
