what about emissivity and absorbtivity of two substances. More over the driving force in conduction and convection depends on temperature difference. See if you don't have any other body in universe no conduction or convection take place from the sole body in universe. Since the energy is...

I worked it out and found that the terms that add heat to after reflection are GP of common ratio (1-a1)(1-a2) which is less than 1. So i got the expression of the form a2 e1 T1*T1*T1*T1 = a1 e2 T2*T2*T2*T2 Thus giving slight change with final result equal to T1 = 0.333 T2

transfer of energy is proportional to difference in temperature only in conduction or convection. But in radiation The amount of heat emitted is independant of other bodies sorrounding it.

Kindly help me coz i don't get the point ur trying to highlit

Background: suppose that we have single body say sphere and nothing else in the universe. Now it will radiate heat depending on its temperature.since its energy is going down its temperature will decrease.Eventually wel have energy in the form of photons and sphere at zero kelvin. thus In...
