Answer:
Heat dissipation is 11.24 KW.
Explanation:
Given that
Temperature of furnace= 1000 K
Temperature of surrounding = 300 K
Also given that both bodies are black bodies so ∈=1
We know heat radiation for black bodies is given as follows
[tex]Q=\sigma A(T_1^4-T_2^4)[/tex]
Now by putting the values in the above formula
[tex]Q=5.67\times 10^{-8} \times 0.2(1000^4-300^4)[/tex]
Q=11.24 KW
So heat dissipation is 11.24 KW.
