Chapter 9.2, Problem 9.5CP

(a)

Interpretation Introduction

Interpretation:

The approximate level of the movable piston in the drawings, the changes in the figure are made at a constant pressure of $\text{1}\text{.0}\text{atm}$ has to be calculated.

Concept Introduction:

Gay-Lussac’s law:

Gay-Lussac law derived from the Charles law,

The law states that a sample gas having fixed pressure is directly proportional to the temperature. Since pressure can never be negative and the temperature scale should be absolute minimum. 

$\frac{\text{V}}{\text{T}}\text{ = constant}$

So the initial and final Volume will be like

$\frac{{\text{V}}_{\text{2}}}{{\text{T}}_{\text{2}}}\text{ = }\frac{{\text{V}}_{\text{1}}}{{\text{T}}_{\text{1}}}$

Here,

V₁ and V₂ are initial and final volume.

T₁ and T₂ are initial and final Temperature.
