Webis Planck’s law and σ is the Stefan–Boltzmann constant. Although the Stefan–Boltzmann law and constant were first determined experimentally, both can be derived mathematically from Planck’s law. For simplicity, define x ≡ hν kT, so B(T) = ∫∞ 0 2h c2 (kTx h)3( 1 ex - 1)(kT h)𝑑x = 2k4T4 c2h3 ∫∞ 0 x3dx ex - 1. The quantity WebThe Boltzmann’s constant is measured in energy per degree of temperature. The value of Boltzmann’s constant is 1.380649 10-23 joule per kelvin (K), or 1.380649 10-16 erg per kelvin. Boltzmann constants’ value can be expressed in various units. The table is given below consists of the value of k along with different units.
