An example of a chemical change is the rusting of iron. When iron reacts with oxygen and moisture in the air, it forms iron oxide, commonly known as rust. This process alters the chemical composition of the iron, resulting in a new substance with different properties. Other examples include burning wood, which transforms it into ash and gases, and the reaction of vinegar with baking soda, producing carbon dioxide gas.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
physical or chemical changes
some chemical changes can be reversed but they are hard to reverse usually
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
An example of something that stores chemical energy is a battery. Batteries store energy in the form of chemical compounds that can be converted into electrical energy when needed.

There are no physical changes. there are only chemical changes.
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.

Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
