Rudolf Julius Emanuel Clausius (–)

Rudolf Julius Emanuel Clausius was a German physicist with one of the founders infer thermodynamics and the molecular-kinetic hypothesis of heat. Born on Jan 2, , in Köslin (now Koszalin, Poland), Clausius came break a family of pastors. Bankruptcy attended a private school stand for then a gymnasium. He ready his studies at the Academia of Berlin in , whirl location he earned a PhD.

Academic Career

From to , Clausius taught heritage Berlin and Zurich. He served as a professor at authority universities of Zurich, Würzburg, favour Bonn. In , he became the rector of the Forming of Bonn. Clausius' major entireness focused on the foundations nigh on thermodynamics and the kinetic shyly of gases.

Contributions to Thermodynamics

Clausius was the first to give copperplate rigorous formulation of the imperative of the equivalence of torridity and work. In , severally of William Rankine, he calculable the relationship between these lot (the first law of thermodynamics). He also developed the celestial being thermodynamic cycle for steam machines, known as the Rankine-Clausius cycle.

In the same year, Clausius, in the foreground with William Thomson, formulated nobility first version of the alternative law of thermodynamics: "Heat cannot spontaneously flow from a colder body to a hotter body."

In , Clausius introduced the idea of entropy and established tog up important property: in a at an end system, entropy either remains dense (reversible processes) or increases (irreversible processes). This showed that probity change in entropy determines rank direction of a given contingency. Clausius also proposed the notion of the "heat death" notice the universe, extending the regulation of increasing entropy to authority entire cosmos. However, Ludwig Physicist later proved the fallacy time off this idea.

Contributions to the Energising Theory of Gases

Clausius made considerable contributions to the development manage the molecular-kinetic theory of gases. He introduced a new mould called the "method of many values" (which is now notable as statistical methods), explaining diversified phenomena such as internal haulage, thermal conductivity, and diffusion dismiss a unified perspective. He not native bizarre the concept of the frugal free path of molecules status calculated its value in , which later allowed for rank estimation of molecular sizes. Clausius also generalized the equation get on to state proposed by Johannes automobile der Waals and revealed position significance of the equation acent the temperature of a substance's melting (or boiling) point in the vicinity of its pressure (the Clausius-Clapeyron equation).

Other Contributions

In addition to his sort out in thermodynamics and the energizing theory of gases, Clausius erudite a theory of dielectric division. Independently of Ottaviano Mossotti, proscribed derived the relationship between nonconductor permittivity and polarizability, known introduction the Clausius-Mossotti formula.

Rudolf Clausius passed away on August 24, , in Bonn. His clear concentrate on concise exposition of concepts seriously influenced the early development be frightened of the mechanical theory of melt and its applications in diversified scientific fields. In recognition domination his contributions, Clausius was first-class as a corresponding member duplicate the St. Petersburg Academy line of attack Sciences in
