WebFeb 12, 2024 · The Boltzmann constant has the units J/K. At room temperature, k B T, is the available energy for a molecule at 25 C or 273K, and is equal to approximately 200 wave numbers. It is important to note that the decision to use the gas constant or the Boltzmann constant in the Arrhenius equation depends primarily on the canceling of the units. WebThe radiation energy per unit time from a black body is proportional to the fourth power of the absolute temperature and can be expressed with Stefan-Boltzmann Law as. q = σ T 4 A (1) where. q = heat transfer per unit time (W) σ = 5.6703 10-8 (W/m 2 K 4) - The Stefan-Boltzmann Constant. T = absolute temperature in kelvins (K)
WebThe SI unit of the Boltzmann constant is J/K and its value is 1.380649×10 −23. As the constant is used for microscopic constraints, the energy is expressed in terms of eV and thus the unit becomes eV/K. The value in this unit is 8.617333262×10 −5. It can also be expressed in the CGS unit which is erg/K.
