(also Nernst's heat theorem, Nernst theorem, Nernst's theorem)

noun

Physics Chemistry
  • A theorem in thermodynamics which states that the change in entropy accompanying a chemical reaction between pure crystalline solids tends to zero as the temperature at which it occurs tends to absolute zero.

    Also called the third law of thermodynamics, especially when formulated more generally in terms of the impossibility of reducing the temperature of a system to absolute zero in a finite number of steps.
