Toasting a piece of bread is primarily a chemical change. The heat causes the Maillard reaction, which is a chemical reaction between amino acids and reducing sugars that gives toasted bread its characteristic flavor and brown color. While the physical structure of the bread changes as it becomes firmer and drier, the key transformations involved in toasting are chemical in nature.

When the bread is left in the toaster for too long and becomes black, it undergoes a chemical change. This process, known as combustion, alters the composition of the bread, resulting in new substances such as carbon and smoke. The burning of the bread releases smoke into the kitchen, which is also indicative of a chemical reaction occurring. In contrast, a physical change would not alter the chemical composition of the substance.

No. Toasting simply changes the structure by removing water and causing browning through the Maillard reaction. Toast may be less dense than bread, but this is simply because there is less water - the calories will be identical.
