This is a physical change and might include a chemical change due to the heat involved in taking the bread to its final appearance. the physical change because, there is a change in color(colour) and a slight change in shape depending on the toaster you are using.
Toasting bread is a chemical change because the heat causes a reaction in the starches and sugars present in the bread, resulting in a new substance with different properties than the original bread.
Making toast is a chemical reaction because you can't change it back into untoasted bread.The drying of the bread is physical but the actual caramelization or darkening of the outer bread layer is a chemical change. The outer edges of the bread are beginning to char. Generally, a color change is an indicator of a chemical change.
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.
Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction. In simpler words, the bread is being "burned" which is a chemical change as it cannot be reversed. You can't get back the same soft,fluffy, white bread after you toast it.

It is chemical change
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
Toasting bread represents a chemical change.
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.
It is a chemical change because some compounds from bread are thermally decomposed.
Toasting a slice of bread is actually a chemical change, as the heat causes a chemical reaction in the bread that results in browning and changing its texture. This irreversible process is different from a physical change, which does not alter the chemical composition of the substance.
