Making bread involves a step called leavening (usually), and that's the part of the operation where your question regarding bread making chemistry is pointing. A leavening agent causes gas to be produced. Be sure to read enough to differentiate the effect of steam (created inside the dough mass) on the finished bread from leavening. Point your cursor to the link and surf on over to our friends at Wikipedia to get the straight scoop. These folks are down with it.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Chemical.
A change from one or more substances to another is a chemical change.
It is physical. The wire changes shape, but it is still made of the same materials.
A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
Toasting bread is a chemical change because the heat causes the chemical composition of the bread to change, resulting in the browning or caramelization of the sugars in the bread. This change is irreversible, unlike physical changes such as cutting or crushing bread.
Leavened bread was made with ingredients possessing the chemical properties necessary to make dough rise

No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
I think you are talking about a chemical change,
Chemical change
physical because its doesn't matter if toasted or not it's still made out of bread or might be chemical cause if it changes colors that's one of the signs of a chemical change look it up on goggle this is some peoples opinion so u don't know if it's right or not
Everything that is made intentionally or with human interference is considered to be an artifical change. If something is altered due to natural process it is considered physical.
Despite the huge amount of chemicals put into modern bread there is no move yet to call bread a chemical. Thus it has no specific chemical formula. Bread is mostly comprised of starch and cellulose, both of which are massive molecular constructs of basic sugars. Thus bread is mainly Carbon, Hydrogen and Oxygen.
Yup. Amino acids are chemically bonded together. That's a chemical change. There are also other non-chemical bonds that form the secondary, tertiary and quarternary structure of proteins...
It is? I thought it was a physical change, because you are changing the look, taste, scent, and feeling of the bread. But it might be a chemical change because you are burning the bread, or oxidizing the surface.
There are two kinds of changes - physical and chemical. It depends on how the change is made.
