nernst heat theorem การใช้
- The first formulation is known as the Nernst heat theorem, and can be phrased as:
- The significance of the Nernst heat theorem is that it was later used by Max Planck to give the third law of thermodynamics, which is that the entropy of all pure, perfectly crystalline homogeneous materials is 0 at absolute zero.
- His investigation of electrochemical potentials at low temperatures was among the work that led, in the hands of others, to the Nernst heat theorem and the Third law of thermodynamics, although not without heated debate between Nernst and Richards.
- However, it is known from thermodynamics that the slope of the ?G curve is-?S . Since the slope shown here reaches the horizontal limit of 0 as T ?! 0 then the implication is that ?S ?! 0, which is the Nernst heat theorem.
