Calculate the energy radiated in one minute by a blackbody of surface area `100 cm^(2)` when it is maintained at `127^(@)C` .

Text Solution

Verified by Experts

T = 273 + 127 = 400 K , ` simga = 5.67 xx 10^(-8) W//m^(2) . K^(4)`
The energy radiated , Q = ` A sigma T^(4)t`
` = 10^(-2) xx 5.67 xx 10^(-8) xx (400)^(4) xx 60`
` = 5 .67 xx 256 xx 6 xx 10^(-1) = 871 J`
