Chapter 7, Problem 7.43EP

Interpretation Introduction

Interpretation:

The simpler gas laws does the combined gas law revert when the pressure is held at constant has to be determined.

Concept Introduction:

Charles’s Law tells that the relationship between temperature and volume of a gas.  The law states that at constant pressure the volume of a fixed amount of gas (the number of moles) is directly proportional to the temperature in Kelvin units.  The mathematical expression for the relationship between volume and Kelvin temperature according to the Charles’s law can be shown as follows,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

  Where,

$\begin{array}{l}{V}_1=Thevolumeofagasatagivenpressure.\\ T_1=TheKelvintemperatureofthegas.\\ V_2=Thevolumeofthegasunderanewsetofconditions.\\ T_2=TheKelvintemperatureofthegasunderanewsetofconditions.\end{array}$

Combined gas law tells that the Kelvin temperature of gas is directly proportional to the pressure and volume of a fixed amount of gas.  The mathematical expression for combined gas law can be represented as follows,

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$
