digesting food is a chemical change because-
1)it is irreversible and permanent.
2)it involves heat change(heat energy is evolved).
3)the final products cant be changed into original form by simple physical methods.
4)C6H12O6=co2+h2o+heat energy
Forage matter that is either digested or being digested, depending on which stomach chamber you are referring to.
Vomiting
Yes it is a change of state when the food is being digested. Solid food particles are changed into semisolid type of liquid in the stomach where it is further digested. Food molecules have to be changed into simple units before it can be absorbed into our cells.
you're vomiting

Starch turns into sugar while being digested inside your stomach.
i have no idea ask somebody else
Yes because the food is chemically changing for example if you eat a hamburger it is not gonna come out as a hamburger when you go to the bathroom because your body digested it which chemically changed it.;)
The stomach has a lining of protective mucus.
In the stomach, primarily proteins are being digested. The stomach secretes enzymes like pepsin and hydrochloric acid that break down proteins into smaller peptides and amino acids. Lipids and carbohydrates also undergo some digestion in the stomach, but protein digestion is the main focus.
Flat tires is a sign of physical change. The tires go from being normal, to then being flat. This changes their physical form.
That is a physical change - at least the pump is (air in, air out, with no chemical change). The energy required to run the pump probably will come from a chemical reaction though: an electric generator burning fuel to run the generator or food being digested and converted to energy in the muscles if it is a person powering it
