Chapter 5, Problem 5.176QP

(a)

Interpretation Introduction

Interpretation:

The volume of air has to be estimated.

Concept Introduction:

Look up or estimate the volume of a typical bicycle tube.

Convert gauge pressure to absolute pressure, and calculate the moles of gas under the conditions given.

Boyle’s law states that the volume of a sample of a gas at constant temperature is inverselyproportional to pressure.

  $\begin{array}{l}\text{V=}{\text{k}}_{\text{1}}\frac{\text{1}}{\text{P}}\text{(or)}\\ {\text{P}}_{\text{1}}{\text{V}}_{\text{1}}{\text{= P}}_{\text{2}}{\text{V}}_{\text{2}}\left(\text{at constant temperature}\right)\end{array}$

(b)

Interpretation Introduction

Interpretation:

The gauge pressure in the tire after three full strokes of the pumphas to be estimated.

Concept Introduction:

Boyle’s law states that the volume of a sample of a gas at constant temperature is inverselyproportional to pressure

  $\begin{array}{l}\text{V=}{\text{k}}_{\text{1}}\frac{\text{1}}{\text{P}}\text{(or)}\\ {\text{P}}_{\text{1}}{\text{V}}_{\text{1}}{\text{= P}}_{\text{2}}{\text{V}}_{\text{2}}\left(\text{at constant temperature}\right)\end{array}$
