Equality of this property is transitive according to the zeroth law of thermodynamics, and the heat flow in a reversible process equals the entropy change times this quantity.
Resonant scattering of Lyman-alpha photons raises the spin type of this property above the kinetic variety. The Saha equation is used to define the ionization type, while the brightness type is given by equating the specific intensity at one wavelength to the Planck function. The effective type is proportional to the surface flux to the one-fourth, from the Stefan-Boltzmann law. Equality of this property is transitive according to the zeroth law of thermodynamics, and the heat flow in a reversible process equals the entropy change times this quantity. FTP name this property measured by the absolute Rankine and Kelvin scales.
