What is the Equilibrium State in Radiation Heat Transfer?

[imselva]

TL;DR

I have two bodies, one at a higher temperature say 1000°C (Body A) and the other is at 22°C (Body B).
Body A emits Radiation (Surface to Surface interaction). The temperature of Body A is maintained by a constant supply of Energy.
The Body B will absorb the Radiation Energy from Body A, and its internal Energy is increased.
How long will it take for Body B to reach higher temperature (Say 500 or even 1000°C).
Please let me know the science behind this Radiation heat Transfer Equilibrium

The time it takes will depend how fast heat energy is transferred, and some qualities of the materials. Amount of heat transferred depends on some factors: a couple are difference in temperature between the 2, surface area (those are not the only factors).
In general, the heat transfers faster if the temperature difference between the two is larger. Larger surface area facilitates faster transfer, as well.

Also, the "body B" may be losing heat to the surroundings, depending on the conditions.

I hope this helps.
