**thermo-dynamic**, a conjunction of the parts 'thermo-' (1663) and '-dynamic' (1827), is a term used in 1849 by Scottish mathematical physicist William Thomson in reference to a Carnot engine, one that is reversible.Overview

In 1849, Scottish mathematical physicist William Thomson, in his "An Account of Carnot's Theory of the Motive Power of Heat

*",*stated:*[1]*“A perfect thermo-dynamic engine is such that, whatever amount of mechanical effect derived from a certain thermal agency; if an equal amount be spent in working backwards, an equal reverse thermal effect will be produced.”

Thomson would later go on to be the first to coin the term "thermo-dynamics" as a subject in 1854.
