A black body of temperature T is inside chamber of `T_0` temperature initially. Sun rays are allowed to fall from a hole in the top of chamber. If the temperature of black body (T) and chamber `(T_0)` remains constant, then A. Black body will absorb more radiationB. Black body will absorb less radiationC. Black body emit more energyD. Black body emit energy equal to enrgy absorbed by it

Answer» Correct Answer - A::C::D
(a,c,d)
Since sun rays fall on the black body, it will absorb more
radiation and since, its temperature will emit
more radiation. The temperature will remain same only when
energy emitted is equal to energy absorbed.
