The radiated power of a body at \(400 \mathrm{~K}\) is \(1000 \mathrm{~W}\). If the temperature is raised to \(800 \mathrm{~K}\), what would be the radiated power of the body?
- A 12000 W
- B 15000 W
- C 16000 W
- D 18000 W
Answer & Solution
Correct Answer
(C) 16000 W
Step-by-step Solution
Detailed explanation
The radiated power of a body, \(P_1=1000 \mathrm{~W}\) Temperature, \(T_1=400 \mathrm{~K}\) As, we know that according to Stefan's Boltzmann's law, Radiated power \(\propto\) (Temperature \()^4\) \(\therefore\) If the radiated power at temperature \(T_2=800 \mathrm{~K}\) is…
