Life and Career
Walther Nernst was born on 25 June 1864, in Briesen, Prussia.
- Nernst Equation: One of Nernst’s most notable contributions was the development of the Nernst equation in 1889, which describes the relationship between the electric potential of an electrochemical cell and the concentration of ions within it. This equation is fundamental in the study of electrochemistry.
- Thermodynamics: Nernst made significant advances in the field of thermodynamics, particularly in the area of heat capacity and the third law of thermodynamics, known as Nernst’s heat theorem.
- Electrochemistry: He conducted extensive research in electrochemistry, which included work on electrolysis, ion transport, and the electrochemical potential.
- Professorships: Nernst held academic positions at various institutions, including the Universities of Göttingen, Leipzig, and Berlin.
Walther Nernst passed away on November 18, 1941, in Muskau, Germany.
Award and Legacy
Nernst was awarded the Nobel Prize in Chemistry in 1920 for his work on the third law of thermodynamics, which addresses the behavior of substances as they approach absolute zero temperature. He formulated the Nernst heat theorem, which provides insights into the behavior of matter at extremely low temperatures.
- Walther Nernst’s work in electrochemistry and thermodynamics had a profound and lasting impact on the field of physical chemistry.
- His Nernst equation is still widely used today to calculate cell potentials in electrochemical reactions.
- The Third Law of Thermodynamics, which he formulated, is fundamental in understanding the behavior of matter at extremely low temperatures.
- Nernst’s contributions to science and his Nobel Prize recognition solidified his legacy as a pioneering scientist in the early 20th century.
