You place a piece of bread in a toaster. A minute later, the toast pops up. What evidence tells you an increase in temperature caused a chemical change?

if your not able to reverse it that means it is a chemical change and with toast you cant reverse the color if the color has changed that most likely means it is a chemical change.

like poles repel so keep pushing north to north and repels funny to see this
