Question

A body is at temperatures the heat energy radiated is

Answer 1

The total radiant heat energy emitted by a surface is proportional to the fourth power of its absolute temperature (the Stefan–Boltzmann law). The rate at which a body radiates (or absorbs) thermal radiationdepends upon the nature of the surface as well.

Answer 2

The total radiant heat energy emitted by a surface is proportional to the fourth power of its absolute temperature (the stefan Boltzmann law) .The rate at which a body radiate(or absorbs) thermal radiation depends upon the nature of the surface as wall
