Final answer:
An exothermic perm generates its own heat through a chemical reaction when the perm solution reacts with the hair, similar to iron oxidation in chemical hand warmers.
Step-by-step explanation:
Type of Perm that Generates Heat
A type of perm that generates its own heat through a chemical reaction is called an exothermic perm. In this process, the chemicals applied to the hair initiate a reaction that produces heat. Similar to exothermic reactions in chemical hand warmers and other day-to-day processes, the perm solution reacts with the hair's natural structure, allowing the hair to mold around the forms that create the curls or waves desired. This chemical process can be likened to other exothermic reactions where heat is spontaneously released, such as the iron oxidation reaction described with the chemical equation: 4Fe(s) + 3O₂(g) → 2Fe₂O₃(s), which shows the process in chemical hand warmers generating heat when iron and oxygen react.
