Two identical objects A and B are at temperatures `T_A` and `T_B`. Respectively. Both objects are placed in a room with perfectly absorbing walls maintained at a temperature `T(T_AgtTgtT_B)`. The objects A and B attain the temperature T eventually. Select the correct statements from the following:

Options

A. A only emits radiation while `B` only absorbs it untilboth attain the temperatures `T` .
B. A loses more heat by radiation than it absorbs, while `B` absords more radiation than it emits until they attain the temperature `T`
C. Both `A` and `B` only absorb radiation but do not emit it they attain the temperature `T` .
D. Each object continous to emit and absorb radiation even after attaiing the temperature `T` .

Answer

B, D

Explanation

`B,D` Every object emits and absorbs the radiation simultaneously If energy emitted is more than energy absorded, temperature falls and vice versa .
