4 A human body has a surface area of approximately 1 m The normal body temperature is 10 K above the surrounding room temperature To Take the room temperature to be To 300 K For To 300 K the value of o 460 Wm 2 where o is the Stefan Boltzmann constant Which of the following options 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 AT To then to maintain the same body temperature the same living human being needs to radiate AW 40T3ATO 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
