What is pyrotic definition?

As an AI language model, I am not sure if you meant "Pyrotic" or "Pyretic." Here's some information on both terms:

Pyrotic (adjective): This term refers to something that is related to or involves fire or combustion. A pyrotic reaction is a chemical reaction that generates heat and light, typically involving the use of oxygen as an oxidizing agent.

Pyretic (adjective): This term refers to something that causes or relates to fever or heat. For example, a pyretic substance is one that raises body temperature, while a pyretic disease is one that causes a fever. Pyretic reactions can refer to chemical reactions that generate heat, rather than light, as in the case of pyrotic reactions.
