work doesn't allways turn into heat calmatory.

your right in the sense that there's alot of work or "interaction" between different surfaces that end up as heat. but your also forgetting the issue with atoms combining changing the structure. ei: chemical, radioactive and physical through other work.

heat is just a measurement of how "active" molecules are in a given medium.


explain this then, if heat is the one thing everything turned into what's the cause of heat?
