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:A. A only emits radiation while B only obsorbs it until both attain the temperature TB. A loses more heat by radiation than it absorbs, while B absorbs more radiation than it emits, until they attain the temperature TC. Both A and B only absorb radiation, but do not emit it, until they attain the temperature TD. Each object continuous to emit and absorb radiation even after attaining the temperature T. |

Answer» Correct Answer - B::D Every object emits and absorbs the radiation simulaneously. If energy emitted is more than energy absorbed, temperature falls and vice versa. |
