1.	A blackbody of surface area 1 cm2 is placed inside an enclosure. The enclosure has a constant temperature 27∘ C and the blackbody is maintained at 327 ∘ C by heating it electrically. What electric power is needed to maintain the temperature?σ=6.0×10−8W/m2−K4.
Answer» A blackbody of surface area 1 $c m^{2}$ is placed inside an enclosure. The enclosure has a constant temperature 27 $^{\circ}$ C and the blackbody is maintained at 327 $^{\circ}$ C by heating it electrically. What electric power is needed to maintain the temperature? $σ = 6.0 \times 10^{- 8} W / m^{2} - K^{4}$ .
