WebNov 8, 2024 · The Boltzmann constant is a critical factor in proportionality. The physical constant that connects a gas particle’s average kinetic energy to its temperature is known as the Boltzmann constant in thermodynamics. The symbol for it is kB or k. The Boltzmann constant value can be measured using J/K or m2Kgs-2K-1. WebNov 8, 2024 · According to Boltzmann, the probability that a randomly-sampled particle will be found to be in state n (giving it an energy En) is given by: P(En) = Ae − En / kBT The coefficient A is a constant that assures that this is a probability, T is the temperature of the collection of particles, and kB is the constant that bears Boltzmann's name.
