A small hole is made in a hollow enclosure whose walls are kept at 600 K. Find the energy emitted per square metre per second in joule (nearest whole number; $σ = 5.67 \times 1 0^{- 8}$ ).

Answer:

7348

Solution:

$E = σ T^{4} = 5.67 \times 1 0^{- 8} \times 60 0^{4} = 7348$ J $m^{- 2}$ $s^{- 1}$ .
