The boltzmann constant k b or k, named after its discoverer, ludwig boltzmann, is a physical constant that relates the average relative kinetic energy of particles in a gas with the temperature of the gas. Stefanboltzmann law recall planck function b t 2hc2 5 exp hc kt. Name of physical constant, specified as lightspeed, boltzmann, or earthradius. This is known as stefanboltzmann law, which states that the rate of outward radiative energy per unit area emitted by an object with temperature t is proportional to the 4th power of t the higher the temperature of an object, the greater its radiative energy output will be the stefanboltzmann constant. Boltzmann factor this is one of the most powerfu l tools in statistical physics can use it to find the probability of finding the system in any particular microstate, when the system is in thermal equilibrium with a rese rvoir at temperature t simple system to consider firs t. Collisions can be thought of as being instantaneous. In statistical mechanics and mathematics, a boltzmann distribution also called gibbs distribution is a probability distribution or probability measure that gives the probability that a system will be in a certain state as a function of that states energy and the temperature of the system.
