Answer:
Step-by-step explanation:
For amount of radiation from a hot body there is Stefan's Boltzman's law which is given below .
E = e σ T⁴
E is amount emitted , e is emissivity , σ is stefan's constant = 5.67 X 10⁻⁸ W / m² . for earth e =.85 approx
E = .85 x 5.67 X 10⁻⁸ x T⁴
604 = .85 x 5.67 X 10⁻⁸ x T⁴
604 = 4.82 x 10⁻⁸ T⁴
T⁴ = 125.31 x 10⁸
T = 3.3457 x 10²
= 334.57K
Temperature in Celsius = 334.57 - 273
= 61.57 Celsius .
