Chapter 14, Problem 50GP

To determine

To find : Temperature rise of the body.

Answer to Problem 50GP

  $2.285°\text{C}$

Explanation of Solution

Given:

Mass of man $=70$ kg,

Heat generate $=200$ kcal/h

Formula Used :

  $\begin{array}{l}\eta =\frac{\text{output}}{\text{input}}\\ Q=ms\Delta T\end{array}$

Calculation :

Heat generated $=200\times \frac{80}{100}=160$ kcal/h

  $\Rightarrow H=160$ kcal/h

  $\Rightarrow 160=70\times L\times \Delta T$

  $\Rightarrow \Delta T=\frac{160}{70}=2.285°\text{C}$

Conclusion :

Hence body temperature will be rise by $2.285°\text{C}$
