Physical: Chewing to make the food particles smaller.
Chemical: Reactions with enzymes to break down the food so the body can use it.
Boiling is a physical change.
im not 100% sure but i believe its a chemical change mostly because a chemical change is when the molocules themselves change to create something else and physical is when the molocules only rearange themselves they don't change at all. seeing as how when you digest you do change whatever you have eaten by breaking it down with the acids in your stomach turning it into what comes out next.
Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
The melting of the wax is a physical change. The burning the of wick is the chemical change
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Its a chemical change.
chemical digestion due to the saliva breaking down food or other things in your mouth.
Digestion of food is a combination of physical and chemical changes. Physical changes occur as food is broken down into smaller pieces through chewing and grinding. Chemical changes take place as enzymes in the digestive system break down food into simpler molecules that can be absorbed by the body.
Chemical changes take place on the molecular level
It is a physical change
what is responsible for chemical digestion in earthworms
Were does chemical digestion take place

The movement of a textbook is a physical change, not a chemical change. Physical changes involve alterations in the appearance or state of a substance without changing its chemical composition. Moving a textbook from one place to another does not alter the chemical makeup of the textbook.
Physical because no reaction is taking place.
