Is toasted bread a physical or a chemical change?
Toasting bread is a chemical change because the heat causes the chemical composition of the bread to change, resulting in the browning or caramelization of the sugars in the bread. This change is irreversible, unlike physical changes such as cutting or crushing bread.
Explain what is an irreversible change and give an example?
An irreversible change is a process that cannot be undone or reversed. Once the change occurs, it is permanent and cannot be restored to its original state. An example of an irreversible change is burning a piece of paper: once the paper is burnt, it cannot be turned back into its original form.

Is burning bread a physical or chemical change?

This change is irreversible and produces a color and chemical composition different from the original bread.
What is the type of change of baking bread?
The type of change that occurs when baking bread is a chemical change, where the heat causes the proteins and starches in the dough to undergo a series of complex reactions, resulting in the formation of new substances such as carbon dioxide gas, steam, and various flavor compounds. This chemical change is irreversible and leads to the creation of the final baked bread with its unique texture and flavor.
Is slicing bread a reversible change?
