Because your $1,000 toaster is broken.....please buy a new one!! :)
It is a chemical process.
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.
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.
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.
Do you mean WHY DOES TOAST TOAST? Because it's heated and turns brown.
Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
no because charcoal is rock, toast is bread, which is food. so no.
chemical
Burning is an irreversible change.
By burning the toast, or any other food, you are definitely reducing its nutritional value. As far as carcinogens, there are some in every cooked food.

Burning toast
You can use a toaster oven to toast. However, you can not bake and toast at the same time. That would lead to burning the toast.

Burning your tongue on hot toast is an example of heat transfer by conduction. Conduction is the transfer of heat through direct contact between objects at different temperatures.
