By Stefan–Boltzmann set of formulae.
Explanation:
The Stefan–Boltzmann law describes the power(energy) radiated from the ideally absorptive black body .
Transference of heat by emission and later absorption of electromagnetic radiation (via waves) between two bodies.

Q = heat transfer per unit time (W)
The S.-B. constant:
T = absolute temperature in Kelvin (K) :
T1= of the first object , T2= of the second object.
A = area of the emitting body
