From the moment ingested food is exposed to saliva to acids in the stomach until it is absorbed into the blood in the stomach or intestines different food products are undergoing chemical change.
The burning of gasoline is a chemical change. The evaporation of gasoline is a physical change. This is a physical change because it is a change in state of matter (from liquid to gas).
neither are chemical changes they are both physical changes
Toasting bread represents a chemical change.
The teeth grinding is a mechanical change. The saliva mixing in with the food and starting the digestive process would be a chemical change.

Drying clothes represents a physical change, not a chemical change. The process simply converts liquid water to gaseous water, so it's only a change in state.
No. Peristalsis is a physical process in which the involuntary muscles of the digestive tract contract and move food along.

Corrosion represents a CHEMICAL change.
Chewing the food is a physical change, but once the food mixes with saliva it becomes a chemical change. Digesting it is definitely a chemical change, because the stomache acids mix with the food and viola a chemical change.
Rusting of a metal, be it a car or any other item, represents an oxidation reaction, and this is a chemical change because the metal is becoming a metal oxide in the process.
Spoiled food of any kind represents a CHEMICAL change.
It is impossible
