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
