Answer and Explanation:
- Stefan-Boltzmann law. Stefan-Boltzmann law, expresses that the all out brilliant warmth power transmitted from a surface is corresponding to the fourth intensity of its total temperature.  
- The law applies just to black bodies, hypothetical surfaces that assimilate all occurrence heat radiation.  
- From the relationship which is an adjustment to Astronomy, of Stephen's Law:  
        ![L = [RT^{2}]^{2}](https://tex.z-dn.net/?f=L%20%3D%20%5BRT%5E%7B2%7D%5D%5E%7B2%7D) 
  
where  
L = Luminosity  
R = Radius  
T = Temperature  
"Bigger" alludes to the radius,  
"Bluer" for the temperature scale and  
"Brighter" to glow in the articulation.
