Chapter 2, Problem 2.31NP

Interpretation Introduction

Interpretation: The increase in temperature needs to be determined after 2.5 hours if an adult is in a thermally insulating barrier and the heat evolved by metabolism is absorbed by the body. The heat capacity of body is $4.18\text{ J/g K}$ and heat produced by the metabolism is $9.4\text{ kJ/ kg hr}$ .

Concept Introduction: The change in temperature can be takes place using the following relation:

  $\Delta T=\frac{q}{C_P}$

Here, q is amount of heat involved in the process and $C_P$ is heat capacity at constant pressure.
