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.
it is a chemical change because heat is a sign of a chemical reaction! :) Hope thos helps!! I learnt it in my science class!
Toasting a piece of bread is a physical change because when the bread is toasted we get the same bread and no new substance is formed
Physical cause it is still bread
chemical
It is a chemical change because some compounds from bread are thermally decomposed.
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.
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.
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.
Chemical Change - Someone toasting bread until it is crisp. (Or just cooking in general, but does not apply to all types of food)Physical Change - Someone pouring one of those Crystal Lights into water.

It is a chemical change because you can not return it to bread
Toasting bread represents a chemical change.
It is a chemical change because some compounds from bread are thermally decomposed.
No it's a chemical change as you can't 'untoast' the bread.
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.
