Chewing food is not a chemical change, it is Physical. all you are doing is crushing down the food inside your mouth, not changing the actual substance.
It is both.
It is a physical change because when you chew your food you break it up into smaller pieces and are therefore changing its size and shape which are physical changes.
However, digestion begins in the mouth. When we chew our food, it mixes with enzymes from our saliva and begins to break down the food. Digestion is a chemical change.
Chewing a cookie is physical change. It's a physical change, because the cookie is now in smaller pieces, but it did not change into a new substance. It's appearance changed, but not the cookie itself.
Because it is irreversible
The bread cannot be gotten back as it was
Simply breaking a cookie or any other object is a physical change.
chewing food is physical damage because you are harming the way it looks not the substance that it is.
Baking cookies would be a chemical change because you are taking a mixture of multiple compounds and converting them at high temperature to other compounds.
Physicals because you are divouring the cookie!
Chewing by itself is a physical change. However, when your saliva (spit) starts to mix with the chewed cookie, a chemical change starts.
physical.
Baking a pie is a chemical change because the cells of the ingredients are broken down when they get hot. You can see this when the crust becomes firm or the fruit in a pie becomes soft.
Yes! Wanna cookie?
Typically, a cookie sheet is aluminum.
yes, a cookie is a solid, because if you mix it, it is hard, then, after you bake it it is even more of a solid than it was as the cookie mix!
Mixture
no,it is a chemical change because the cookies change shape and smell,don't they?
Nope. That is a physical change. If I crush a cookie into powder, it is still cookie- no chemical change. The form and appearance have changed. But pour powdered cookie onto your tongue, and it is still cookie.
It's a physical change, but not much of one.
A cookie is not a chemical reaction but BAKING the cookie is.
No.
Baking a pie is a chemical change because the cells of the ingredients are broken down when they get hot. You can see this when the crust becomes firm or the fruit in a pie becomes soft.
Yes! Wanna cookie?
When you see a cookie, and then eat the cookie, the cookie first goes into your stomach after you're through chewing. Once there, the cookie is broken down by the acids in the stomach and sent through the intestines where it is further digested.
Yes i was taught this last year in science
Considering the ratio of the amount of cookie that he swallows to the amount of cookie that flies all over the place while he's chewing, I imagine that he could keep doing that until his jaw gets tired.
well cookie dough has the ability to be cooked
yes, it has baking soda or baking powder, sometimes both. As these are chemical leaveners this makes a cookie a chemical property.
