Mixing chemicals can be EXTREMELY dangerous, they might not be but do NOT try it.
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.
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.
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.
