6. Rudolf Clausius
was a German physicist and mathematician best known for formulating the second law of thermodynamics. His estimated IQ scores range from 190 to 205 by different measures. Clausius made thermodynamics a science, coined the term "entropy," and developed the kinetic theory of gases.He was also one of the first scientists to suggest that molecules are made up of continually interchanging atoms, which later provided the basis for the theory of electrolytic dissociation (the breakdown of molecules into charged atoms or ions).
