Question
The total power radiated by a body of area $5.00 \mathrm{km}^{2}$ and emissivity 0.800 is $1.35 \times 10^{9} \mathrm{W}$Assume that the body radiates into vacuum at temperature 0 K. Calculate the temperature of the body.
Step 1
We know that 1 km = 1000 m, so 1 km² = (1000 m)² = 10⁶ m². Therefore, the area of the body is $5 \times 10^{6} \, m^{2}$. Show more…

A body of emissivity (e = 0.75) has a surface area of 300 cm^2 and a temperature of 227 °C are kept in a room at temperature (27 °C). Using the Stephens Boltzmann law, calculate the value of the net power (in W) emitted by the body. (σ = 5.67x10^-8 Wm^-2K^-4)
Assume that the total surface area of a human body is $1-6 \mathrm{~m}^{2}$ and that it radiates like an ideal radiator. Calculate the amount of energy radiated per second by the body if the body temperature is $37^{\circ} \mathrm{C}$. Stefan constant $\sigma$ is $6 \cdot 0 \times 10^{-8} \mathrm{~W} \mathrm{~m}^{-2} \mathrm{~K}^{-4}$.
A spherical blackbody radiator with a diameter of 1.00m is held at a constant temperature. What is the temperature (K) if the power radiated by the body is 18.0 kcal/min?
