The latter can be estimated as \(D\propto \frac{{k}_{{{\rm{B}}}T}{m}\frac{V}{N{d}^{2}}\), where kB is Boltzmann’s constant, T the absolute temperature, V the volume of the gas, d the particle diameter, m the particle mass, and N the number of particles. Hence, one...
The kelvin scale was initially developed by shifting the starting point of Celsius scale to absolute zero. With the redefining of the SI system in 2019, the kelvin scale has been defined by fixing the numerical value of the Boltzmann constant to 1.380649×10−23 J⋅K−1. The kelvin is...
