Is burning toast a chemical change or a physical 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.

How are we burning toast?
Because your $1,000 toaster is broken.....please buy a new one!! :)
Is burning toast reversible?
Burning toast is not reversible. Once the toast is burned, the chemical composition of the bread changes due to the high heat, leading to the formation of new substances like carbon. While you can scrape off some of the charred parts, you cannot return the toast to its original state.
Is a toast that burns a physical or a chemical change?
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.
Is burning toast is a physical or a chemical change?

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.

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

Is burning toast in the toaster physical or chemical?
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.
