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.

Is toasting bread a physical or chemical change?
It is a chemical change because some compounds from bread are thermally decomposed.
Is toasting bread an example of a physical or a chemical change?
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.
Is toast physical change or chemical change?
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.
Is burning toast in the toaster physical or chemical?
Yes, it is. The process by which heat changes the molecules of the bread from white and soft to brown and crispy is a chemical change. A chemical change does NOT mean you have to add chemicals. It just means the chemicals (molecules) in the substance changed their chemistry. So slicing bread is a physical change, but toasting it is a chemical change.
What is an example of a physical and chemical change that you might observe in the school cafeteria?
