Chapter 12, Problem 9PE

(a)

Interpretation Introduction

Interpretation:

Final pressure of gas if volume is reduced from $725\text{ mL}$ to $283\text{ mL}$ has to be determined.

Concept Introduction:

Boyle’s law represents inverse relation of volume of fixed mass of ideal gas with its pressure at fixed temperature.

Mathematically relation for Boyle’s law is as follows:

  $V\propto \frac{1}{P}$

Or,

  $P_1{V}_1=P_2{V}_2$

Here,

$P_1$ is initial pressure.

$P_2$ is final pressure.

$V_1$ is initial volume.

$V_2$ is final volume.

(b)

Interpretation Introduction

Interpretation:

Final pressure of gas if volume is change from $725\text{ mL}$ to $2.87\text{ L}$ has to be determined.
