THERMODYNAMICS - CASE STUDY
    Introduction


Temperature Taking

 

A nurse is taking care of three children. She needs to measure their temperatures and compare the temperatures with the standardized body temperature to determine if someone got a fever.



Thermometer		  

What is known:
The standardized body temperature for different age people is shown in the table.

Age Temperature (oF)
0 - 3 month 99.4
3 - 6 month 99.5
6 -12 month 99.7
1 - 3 year 99.0
3 - 5 year 98.6
5 - 9 year 98.3
9 - 13 year 98.0
> 13 year 97.8 - 99.1

The temperature of the three kids are:

Age Temperature (oC)
3 month 37.0
6 month 38.5
3 year 37.2
     
    Questions


 

Is there someone who got a fever?

    Approach
   

The relation between oC, oF and K are:
      T (K) = T (oC) + 273.15
      T (oF) = 1.8 T(oC) + 32.0
