Answer:
925.04 J/s
Explanation:
T = 80 C = 80 + 273 = 353 K
To = 20 c = 20 + 273 = 293 K
A = 2 m^2
Use the formula for Stefan's law
Energy radiated per second
[tex]E = \sigma A \left ( T^{4}-T_{0}^{4} \right )[/tex]
[tex]E = 5.67 \times 10^{-8}\times 2\left ( 353^{4}-293^{4} \right )[/tex]
E = 925.04 J/s
