they become acidic and actually become a whole different shade due to the compounds in your saliva, the atoms in it also begin to separate due to your teeth when you chew :D:D Hope this helps
Hai
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.
The chemical change that occurs in green plants when they manufacture food is known as photosynthesis. Chloroplasts within plant cells absorb energy from the sun, which is then used to create ATP molecules to store chemical energy for later use.
the physical change in the change in food when the enters esophagus is when it has a chemical breakdown in your mouth with a mechanical breakdown the chemical breakdown is when your salivia is making the food moist the mechanical is when you chew the food so it easier for it to enter the esophagus and so the salivia can get it moist then your esophagus uses muscles to push the food down into your stomache
In my living environment, a chemical change occurs when food is digested in the stomach, where complex molecules are broken down into simpler ones. In my non-living environment, a chemical change occurs when iron rusts due to exposure to oxygen and moisture, forming iron oxide.
Well, it can be many things .. For example, cooking. When you heat the food a chemical change occurs within the food.
CHEMICAL CHANGE
Tarnishing of a silver spoon is a chemical change. It occurs when the silver reacts with sulfur compounds in the air or food, forming silver sulfide. This chemical reaction alters the composition of the spoon, resulting in the tarnished appearance.
This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
chemical
food is a chemical change if it is added with other components and turned into a form and if it is taken raw then it is not chemical change because no change is occuring
There are several changes that occur that cause food spoilage. A loss of ph, spoilage caused by bacteria and decomposition are contributing factors to food spoilage.
its a physical joking its a chemical change a physical is one substances, and a chemical change is two or more substances so the answer is to food molding a chemical change
