Question

Consult Multiple-ConceptExample 8 to see the concepts that are pertinent here. Aperson's body is producing energy internally due to metabolicprocesses. If the body loses more energy than metabolic processesare generating, its temperature will drop. If the drop is severe,it can be life-threatening. Suppose a person is unclothed andenergy is being lost via radiation from a body surface area of 1.55m2, which has a temperature of 34 °C and anemissivity of 0.779. Suppose that metabolic processes are producingenergy at a rate of 212 J/s. What is the temperature in kelvins ofthe coldest room in which this person could stand and notexperience a drop in body temperature?

Explanation / Answer

   from the theory we hyave the equation
   Pnet = e A (T4 -To4)
   the temperature conversion will be
   T = 34 + 273
      = 307 K
   To = [T4 -(Pnet / e A)]
        = ..........K
