Description: This metals processing experiment demonstrates the heat released when iron is oxidized. Normal oxidation (rusting) provides the same heat but over a prolonged period of time. Here, the process is rapid and is quite noticeable. This is used commercially to produce hand warmers and related products. Variations in the method and constituents in the reaction demonstrate the influence of variations in processing on the p
roperties of the product.

MatEd Core Compentencies: 0B. Prepare tests and analyze data s to chemical
