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.
What is an example of chemical change that food goes through as you eat it?
An example of a chemical change that food goes through as you eat it is the breakdown of starches into sugars in your mouth through the process of digestion. Saliva contains enzymes like amylase that break down complex carbohydrates into simpler sugars, allowing your body to absorb nutrients more easily. This chemical change is essential for the body to extract energy from the food you eat.
