Chapter 4, Problem 39E

Interpretation Introduction

Interpretation:

The final pressure of a gas due to change in volume by the piston is to be calculated.

Concept introduction:

According to Boyle’s law, the pressure of a gas is inversely proportional to its volume. Mathematically,

$\begin{array}{l}P\alpha \frac{1}{V}\\ \Rightarrow PV=\text{ constant}\\ \Rightarrow P_1{V}_1=P_2{V}_2\end{array}$

Thus, knowing the three parameters out of the four, the fourth one can be calculated using the above equation.
