NEET2002PhysicsThermal Properties of MatterActual
A black body is at a temperature 300 ~K . It emits energy at a rate, which is proportional to
Options
- A300
- B(300)^3
- C(300)^2
- D(300)^4 .
Correct answer
D. (300)^4 .
Step-by-step solution
Temperature of a black body (T)=300 ~K . Stefan's law of radiation states that energy emitted by the black body (E) T^4 (300)^4 .
