When spaghetti is cooked in boiling water and becomes soft is it a physical or chemical change?
It is a physical change: the water is absorbed into the sponge-like pasta. The elements and compounds of the flour and water are not changed, and you could even dry the pasta out again (with a probable loss of quality).
Is swallowing bread a chemical change?
Any form of digestion is a chemical reaction. It begins when you chew with the saliva in your mouth and continues all the way down to your intestine. Bread, which contains mostly starches, is converted into sugars, which in turn provide your body with energy. This is why runners and other athletes sometimes eat pasta the night before they have an event.
Is dry pasta a compound or a mixture?
Dry pasta is considered a mixture rather than a compound. It is made from various ingredients, primarily flour and water, which retain their individual properties and can be separated. In a compound, the components are chemically bonded and cannot be easily separated. Since the ingredients in dry pasta do not undergo a chemical change, they remain a mixture.
What is an example of chemical change that food goes through as you eat it?
A very simple answer is boiling water. If you cook rice, pasta, or if you steam vegetables, then you have to boil water. The water heats up and turns into steam, a gas. Voila, a chemical change. *warning* this answer is incorrect

What is the chemical formula of pasta?
Pasta is primarily made of flour, water, and sometimes eggs. The chemical formula for flour is C6H12O6, for water is H2O, and for eggs is complex due to the presence of proteins, lipids, and other molecules. Therefore, the chemical formula for pasta would be a combination of these molecules depending on the specific ingredients used in the pasta recipe.

What the chemical digestion of pasta in the mouth and stomach?
Chemical digestion of pasta begins in the mouth, where saliva, containing the enzyme amylase, breaks down starches into simpler sugars. As pasta is chewed and mixed with saliva, this enzymatic action initiates the digestion process. Once the pasta reaches the stomach, gastric juices, including hydrochloric acid and pepsin, further break down proteins, though starch digestion continues primarily in the small intestine. Overall, the chemical digestion of pasta involves both enzymatic and acidic processes that transform it into absorbable nutrients.
What kind of changes are physical changes?
Anything that can be observed without a chemical reaction taking place. IE: Ice melting, Water Boiling, The coke bottle you left in your car freezing into a solid brick.
