Do you mean WHY DOES TOAST TOAST? Because it's heated and turns brown.
Chemical
Oxygen is the gas found in the air that is necessary for toast to burn. When toast is heated, it undergoes a combustion reaction where oxygen reacts with the toast to produce heat and light, resulting in the burning process.
Because your $1,000 toaster is broken.....please buy a new one!! :)
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.
It is a chemical process.
Bread becomes toast - when it's heated so the surface of the slice is charred.
