A body at temperature T radiates heat according to relation:
Correct answer: B. T4
- A. T-2
- B. T4
- C. T-4
- D. None of these
Explanation
By the Stefan-Boltzmann Law, for a black body, the amount of heat radiated per unit area is directly proportional to the fourth power of the kelvin temperature. The proportionality constant is called Stefen's constant and has a value of 5.67x10(-8).
