Yes Because you cannot change it back to it's original form
Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
Burning is an irreversible change.
chemical
It is kind of both....The chemical: The toast loses its water molecules and so loses most of its H2O.The Physical: The toast becomes hard and crunchy from soft and airy.Added:The toast burning is a total physical change, not chemical. Water loss from the toast is not a chemical change as species have not changed partners ( atoms have not rearranged into new species ) and H2O remains the molecule H2O, water.

Because your $1,000 toaster is broken.....please buy a new one!! :)
A toast that burns is primarily a chemical change. This is because the process of toasting involves the transformation of bread into toast through the application of heat, leading to the formation of new substances such as carbon and various gases due to the Maillard reaction and caramelization. The burning of the toast results in irreversible changes, indicating that a chemical change has occurred.
Burning toast is a CHEMICAL change. A physical change is reversable-for example, you can freeze water into a cube and then defrost and reconvert to water. Burning is always a chemical change. In order for something to burn, some of the original substance must be lost and therefore cannot be turned back into its original form
because it can no be reversible once it has been burnt it cannot be turned back into bread or slightly toasted toast, that is its permanent form :D
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
no because charcoal is rock, toast is bread, which is food. so no.
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.
