Oxidizing food for energy-physical change?
Oxidation is a chemical process.
Why is spoiling food a chemical change?
Food spoilage is a chemical change because it is caused both by oxidation of fats and the chemical changes involved when fungi and bacteria use enzymes to use the food for its own development.
Why metabolism of food in the body is a chemical change?
Metabolism of food in the body is a chemical change for the same reason as any other chemical change: New chemical bonds are formed and/or chemical bonds existing in the reactants are broken. Both bond breaking and bond formation occur in metabolism.
How is food a chemical change?
The food it self gets turned into energy for the human body. If food is cooked, if undergores a huge chemical change. From potential(stored) to kinetic(released).
Why is heat or thermal energy released from the chemical energy to food?
Oxidation releases heat. Food is chemically oxidized by the body to produce carbon dioxide, water and heat. There are other chemical processes occurring but this is the primary source of heat from food.
Is the Digestion of food is physical change or chemical change?
Digesting food is a chemical change.
Is Digesting food Physical Property Or Chemical Property Or Physical Change Chemical 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.
Is food spoilage is a chemical change?
CHEMICAL CHANGE
What two places in the body in which food undergoes a chemical change?
stomach and intestines(small and large)
How is the heat energy required to heat the body?
by food oxidation
Is Digestion of food a physical or a chemical change?
it depends on how you look at it. its primarily chemical because without the chemicals in your body like pancreatic juices and hydrochloric acid, you could'nt break them down. but physically you chew your food before you swallow it for those chemical processes to occur. its safe to say however that the CHEMICAL part is absolutely essential for the proper digestion of food.
Is food reacting with pepsin a chemical or mechanical change?
This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
