A human body has a surface area of approximately 1m The normal body temperature is 10K above the surrounding room temperature To Take the room temperature to he To 300K For To 300K the value of oT 460W m where o is the Stefan Boltzmann constant Which of the following options is are correct This question has multiple correct options If the surrounding temperature reduces by a small amount AT To then to maintain the same body temperature the same living human being needs A to radiate AW 40 TATo more energy per unit time B C D If the body temperature rise significantly then the peak in the spectrum of electromagnetic radiation emitted by the body would shift to longer wavelengths 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 The amount of energy radiated by the body in 1 second is close to 60 Joules
