Answer

Brief Explanations:

Physical changes do not change the chemical composition of a substance, while chemical changes result in a new substance with different chemical properties. Toasting marshmallows causes a chemical reaction due to heat - new substances are formed. Rusting is a chemical change as iron reacts with oxygen to form iron oxide. Breaking glass only changes the physical form of glass, not its chemical makeup. Slicing carrots is a physical change as it only changes the shape and size of the carrots. Decaying food is a chemical change as microorganisms break down the food into new substances.

Answer:

Toasting marshmallows is a chemical change. Slicing carrots is a physical change. Decaying or rotting food is a chemical change.
