Thermite process is quite useful for repairing broken parts of machines . Explain. |
|
Answer» Solution :In the thermite process, oxides of metals LIKE iron are reduced by aluminium. This reaction is highly exothermic and a large amount of heat is evolved during the reaction. As a result of large heat, the metal will be the molten state. For example `underset("Iron OXIDE")(Fe_2 O_3) + 2AL(s) overset("Heat")to Al_2 O_3 (s) + underset("Molten")(2Fe +"Heat")` If the molten metal is allowed to fall between the broken PARTS of a MACHINE, the gaps will be filled up. Therefore, the machine will be repaired. |
