WebbStahl expanded Becher's ideas and renamed terra pinguis, calling it phlogiston, from the Greek word phlogos meaning “flame.”. Phlogiston was colorless, odorless, tasteless, and could not be sensed by touch, but it possessed mass. Every combustible substance contained it and released it when it was burned, together with caloric (heat). WebbThe caloric theory of heat as developed by Carnot in his famous "Reflexions on the Motive Power of Heat" (Paris, 1824) leads immediately to the correct solution of the relations between heat and motive power (energy or work) in all reversible processes, and appears to be in some respects preferable to the mechanical theory as a method of …
