Chemical, because the disaccharide in toast when heated become hard thus giving you toast
Yes, it is. You can toast a slice of bread (or marshmallow), or people at a celebration.
This is WHY we call it toast. It is browned bread!! Toast goes brown because of the Maillard reaction. Quote from the Related Link: "The Maillard reaction is a chemical reaction between an amino acid and a reducing sugar, usually requiring heat."
The electrical energy from the toaster is transformed into thermal energy to toast the bread.
Chemical
If it is a doublet, where you change one letter at a time to make another word until you eventually reach toast, then the answer is: bread-->breaK-->bLeak-->bleaT-->bleSt-->blAst-->bOast-->Toast If it's not, then it could possibly be the the "change" of moving the "r" in bread to the end of toast, which would give you toastr. A toaster toasts bread, which would change bread into toast.
Lightning is really hot. If you put a marshmellow somewhere in a thunderstorm, and if it gets struck by lightning, I wouldn't say it'd be toasted. It'd be burnt!
The toaster contains a variable resistor (timer knob on the outside) that changes the charge rate of the capacitors. When the capacitors are fully charged, the release the toast.
it is a physical change
Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
Physical change.
