Chapter 15.1, Problem 3PP

Interpretation Introduction

Interpretation:

The energy in unit yourself is to be converted into joules and Calories.

Concept introduction:

The various conversion factors are:

1 Calorie=1000 calories

$1cal=4.184J$

Answer to Problem 3PP

$1yourself=0.4184J$

$1yourself=1\times {10}^{-4}Calories$

Explanation of Solution

1 Calorie=1000 calories

$1cal=4.184J$

Given data:

$1yourself=0.1cal$

Conversion of ‘yourself’ into joules:

$\begin{array}{c}1yourself=0.1cal\times \frac{4.184J}{1cal}\\ =0.4184J\end{array}$

Conversion of ‘yourself’ into Calories:

$\begin{array}{c}1yourself=0.1cal\times \frac{1Calorie}{1000cal}\\ =1\times {10}^{-4}Calories\end{array}$

Conclusion

Therefore,

$1yourself=0.4184J$

$1yourself=1\times {10}^{-4}Calories$
