Answer:
527 ° C
Explanation:
For black body radiation, the power emitted per unit area is directly proportional to the absolute temperature raised to the fourth power:
j = k T⁴
First, convert 127° C to Kelvins:
127° C + 273.15 = 400.15 K
Now find the constant of variation:
2×10⁵ = k (400.15)⁴
k = 7.80×10⁻⁶
Finally, solve for the temperature at the new rate of radiation:
32×10⁵ = (7.80×10⁻⁶) T⁴
T = 800.3
The temperature is 800 K, or about 527 ° C.
