Question

A black body of temperature T is inside a chamber of temperature $T_0$. Now the closed chamber is slightly opened to sun such that temperature of black body (T) and chamber $\left(T_0\right)$ remains constant

• 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 energy absorbed by it

Answer 1

The correct option is D black body emit energy equal to energy absorbed by it

Since, the temperature of black body is constant,
Total heat absorbed = total heat radiated.
