Question

state kirchoffs law of heat radiation

​

Answer 1

Answer:

Explanation:

With this definition, Kirchhoff's law states, in simpler language: For an arbitrary body emitting and absorbing thermal radiation in thermodynamic equilibrium, the emissivity is equal to the absorptivity. In some cases, emissive power and absorptivity may be defined to depend on angle,

Answer 2

Answer:

With this definition, Kirchhoff's law states, in simpler language: For an arbitrary body emitting and absorbing thermal radiation in thermodynamic equilibrium, the emissivity is equal to the absorptivity. In some cases, emissive power and absorptivity may be defined to depend on angle, as described below.
