Which option states the principle behind the law of conservation of mass and the law of conservation of energy? Energy and mass are the properties that scientists measure when studying physical changes and chemical reactions. Energy and mass cannot be created or destroyed during physical changes or chemical reactions. An object's energy and mass have a direct relationship with that object's temperature. An object's energy and mass have an indirect relationship with that object's temperature.
