Chapter 13, Problem 55A

Interpretation Introduction

Interpretation:

The graph is to be interpreted and to check whether it is following Charles' Law or not.

Concept introduction:

Charles' Law states that at constant pressure, volume is directly proportional to the temperature for a given amount of gas.

Answer to Problem 55A

The data is completely accurate.

Explanation of Solution

Charles' Law states that at constant pressure, volume is directly proportional to the temperature for a given amount of gas.

According to it,

$\frac{V}{T}=constant$, keeping the pressure constant

Now from the graph,

$\begin{array}{c}\frac{V_1}{T_1}=\frac{200}{100}\\ =2\\ \frac{V_2}{T_2}=\frac{400}{200}\\ =2\\ \frac{V_3}{T_3}=\frac{600}{300}\\ =2\end{array}$

Thus the data is accurate.

Conclusion

As V-T graph is straight line graph, so it follows Charles' Law.
