although the reactants are stable at room temperature, they burn with an extremely intense exothermic reaction when they are heated to ignition temperature. the products emerge as liquids due to the high temperatures reached (up to 2500 °c with iron(iii) oxide)—although the actual temperature reached depends on how quickly heat can escape to the surrounding environment. thermite contains its own supply of oxygen and does not require any external source of air. consequently, it cannot be smothered, and may ignite in any environment given sufficient initial heat. it burns well while wet, and cannot be easily extinguished with water—though enough water to remove sufficient heat may stop the reaction. small amounts of water boil before reaching the reaction. even so, thermite is used for welding underwater.
