Answer:
In Celsius:
Explanation:
The formula we are going to use is:
Where:
ε is the emissivity
σ is the Stefan constant
is the final temperature of surrounding surfaces
is the required temperature
is the are of surrounding surface
Calculating The area:
σ= 
ε =0.95
=55+273
=328 K
=100 W
In Celsius:
Answer:
<h2>0.9 Joules</h2>
