Filler metal is obtained from an exothermic reaction between iron oxide and aluminum. |
Inside the mold, the liquid undergoes an exothermic chemical reaction, which forms the polyurethane polymer in the mold. |
The rusting of iron is an exothermic reaction and this process is used in hand warmers which are utilized in cold regions. |
For these exothermic processes, the solubility decreases with an increase in temperature. |
Little heat is needed in the roasting of sulfide ores because the oxidation of the sulfide ion to sulfur dioxide is exothermic. |
Because the emission of radiation involves a loss of energy, chemiluminescent reactions must be exothermic. |
