The amount of radiant energy emitted by a surface is given by q = ɛ0 AT+ where q represents the rate of thermal energy (per unit time) emitted by the surface in watts; e = the emissivity of the surface 0<ɛ<1 and is unitless o = Stefan-Boltzman constant (o = 5.67×10% ) A represents the area of the surface in m² Ty = surface temperature of the object expressed in kelvin What are the appropriate units for o if the equation is to be homogeneous in units?
