Answer 1

The statement that correctly identifies a part of this process as a physical or chemical change is: The toasting of the marshmallow is a chemical change.

To clarify:

• The melting of the chocolate is a physical change since it does not alter the chemical structure of the chocolate.
• The digesting of the food is a chemical change because it involves breaking down the food into its components.
• The burning of the wood for the campfire is a chemical change as it transforms the wood into ashes, smoke, and gases.
• The toasting of the marshmallow involves caramelization and the formation of new compounds, making it a chemical change as well.
