Answer:
A chemical transition is the result of a chemical reaction, whereas a physical change is when the structure of matter changes, but not the chemical identity. Burning, cooking, rusting, and rotting are examples of chemical changes.

Answer:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Example:-
The decomposition of organic matter (for example, rotting food).
