Reflections on the motive power of fire, by sadi carnot. The clausiusclapeyron relation, named after rudolf clausius and benoit paul emile clapeyron, is a way of characterizing a discontinuous phase transition. Melting point of water return to the general form of the clausiusclapeyron equation and make the appropriate substitutions for our two phases liquid water and ice at typical atmospheric conditions near the melting point.
