Calculate the temperature (in K) at which a perfect black body radiates energy at the rate of 5.67W cm^(-2) . Given sigma = 5.67 xx 10^(8)Wm^(-2)K^(-4) .

What is the temperature at which a black body radiates heat at the rate of one kilowatt per unit area ? (Stefan 's constant sigma = 5.7 xx 10^(-8) S.Iunits)

At what temperature, a perfectly black body would radiate energy at a rate of 90.72xx10^(4)W//m^(2) ?

The temperature of a perfect black body is 727^(@)C and its area is 0.1 m^(2) . If Stefan's constant is 5.67 xx 10^(-8) watt//m^(2)-s-K^(4) , then heat radiated by it in 1 minute is:
