It really depends. There is no definite combination that can change into a chemical change. A chemical change is basically a change where the molecules or particles inside the original substance changes its property or what it is.
Here are some examples:
Baking Soda and Vinegar
Iron rusting (its not iron, its rust after the change has gone)
Silver or copper tarnishing
Photosynthesis

Melting snow is a physical change because it changes from a solid state to a liquid state without altering its chemical composition.
Healing a broken bone involves a combination of physical and chemical changes. The bone undergoes physical changes as it reconnects and reforms its structure, while chemical processes occur to help repair and strengthen the bone tissue.
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
- a change in color -a change in odour -bubbling -a change of state (eg. solid to liquid, gas to liquid, etc.) either one or a combination of these things can indicate a chemical change.

Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Cooking food can cause chemical Changes
No, physical changes involve a change in appearance, texture, or state of matter without altering the chemical composition of the substance. In contrast, chemical changes result in the formation of new substances with different chemical properties.
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
The smoke produced by a vehicle is a combination of physical and chemical changes. The combustion of fuel in the engine is a chemical change that produces gases, while the dispersal of these gases into the air involves physical changes such as condensation and diffusion.

Iron is a chemical element, not a change.
