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.

Is butter melting on toast a chemical or a physical change?
it is a physical change
Does the inside of a toaster have chemical energy?
No, assuming that by "chemical energy" you mean "chemical reaction." Toasters use resistance heaters (i.e. relatively thin wires carrying electricity) to impart radiation to the contents. This allows for almost infinite reuse.
Is toast browning a chemical or physical?
Toast browning is a chemical change because it involves the Maillard reaction, where the sugars and amino acids in the bread react to produce new compounds that give the toast its characteristic brown color and flavor. This reaction cannot be reversed by simply changing the physical state of the toast.
Is butter melting on warm toast a chemical or physical property?
It is a physical property. A chemical property would involve the butter reacting to the toast, but the butter is actually reacting to the heat from the toast. The butter would melt against any surface hot enough, where as butter would not melt on cold toast. Hence, the reaction to heat makes it a physical property. (A relatively easy way to remember is that physical properties deal with the transfer of physical energy or force such as heat, inertia, etc. Chemical properties occur when two material substances trade molecules or electrons.)
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
How are we burning toast?
Because your $1,000 toaster is broken.....please buy a new one!! :)
Is burning toast is a physical or a chemical change?
chemical
Is burning toast a physical or chemical state?
It is a chemical process.
Is burning toast a physical change?
Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
Is there such a thing as a toaster oven with also a toaster, so you can toast bread while baking something?
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.
Is a burning toast a physical or chemical change How do you know?
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.

Is a candle more of a chemical change then toast in a toaster?
It is a chemical change.
How much toast could a toaster toast if a toaster could toast toast.?
It depends, how much toast do you have.... It also depends on how many toast your toaster can toast.
Is a toast a chemical or physical change?
Chemical
Burning toast physical or chemical change?
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
What if your friend decides to toast a piece of bread but leaves it iit in the toaster for to long the bread is black and the kitchen is full of smoke is that a chemical or physical change?
When the bread is left in the toaster for too long and becomes black, it undergoes a chemical change. This process, known as combustion, alters the composition of the bread, resulting in new substances such as carbon and smoke. The burning of the bread releases smoke into the kitchen, which is also indicative of a chemical reaction occurring. In contrast, a physical change would not alter the chemical composition of the substance.
