Question

A human body has a surface area of approximately 1 m². The normal body temperature is 10 K above the
surrounding room temperature T₀. Take the room temperature to be T₀ = 300 K. For T₀ = 300 K, and the
value of ???? T₀⁴ =460 Wm⁻² (where ???? is the Stefan-Boltzmann constant). Which of the following option is/are
correct?
[A] The amount of energy radiated by the body in 1 second is close to 60 Joules.
[B] If the surrounding temperature reduces by a small amount ㅿT₀ < temperature the same (living) human being needs to radiate ㅿW = 4????T₀³ ㅿT₀ more energy per unit time
[C] Reducing the exposed surface area of the body (e.g by curling up) allows humans to maintain the same
body temperature while reducing the energy lost by radiation.
[D] If the body temperature rises significantly then the peak in the spectrum of electromagnetic radiation
emitted by the body would shift to longer wavelengths.
