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

Options

A. Black body will absorb more radiation
B. Black body will absorb less radiation
C. Black body emit more energy
D. Black body emit energy equal to enrgy absorbed by it

Answer

A, C, D

Explanation

(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.
