False

Answer 1

False.

The mass of the marshmallow decreased due to processes such as evaporation of water or combustion if it was heated. However, the atoms did not disappear; they may have been transformed into different substances or released into the environment, but the law of conservation of mass states that mass cannot be created or destroyed.
