(also Boltzmann constant) a physical constant relating the average relative kinetic energy of particles in a gas to the temperature of that gas.In 2018 the General Conference on Weights and Measures agreed that, as part of the redefinition of the kelvin, the value of Boltzmann's constant would from May the following year be set at exactly 1.380648 × 10−23 J K−1, having previously been given as 1.38064852(79) × 10−23 J K−1 (where the figure in parenthesis represents the standard uncertainty due to errors in measurement).Boltzmann never directly posited the constant, but he developed the underlying principles from 1877.extracted from Boltzmannn.< as lemmas |
