Self-Clean Ovens with Steam. Avoid the time and door locking required for conventional self-clean ovens. Steam Clean allows for quick cleaning of minor food spills at temperatures lower than the standard self-clean feature. Simply pour 1 cup of water into the bottom of a cool oven. Close the door and select Steam Clean.
Both are chemical reactions, both are oxidation. Burning (combustion) is the oxidation of the fuel source, rusting is oxidation of metal.
Physical changes affect the state of an item, and a chemical change happens at a molecular level. Chemical changes involve atomic bonds being created or broken during chemical reactions. When iron rusts because it is exposed to the oxygen, that is a chemical change. In this instance, the molecules change their structure and become iron oxide.
