Chapter 8, Problem 5RQ

Interpretation Introduction

Interpretation:

The changes of pressure and density of two containers having molecule $\text{X}$ which are converted to ${\text{X}}_{\text{2}}$ should be explained if the volume of one container is not flexible and the other is flexible.

Concept introduction:

• The pressure is directly proportional to the mass of fluid, because pressure is the force acting per area.
• Equation for density is,

       $\text{Density}\text{=}\frac{\text{Mass}}{\text{Volume}}$

• According to ideal gas equation,

$\text{Pressure}\text{=}\frac{\text{Number}\text{of}\text{moles}\times \text{R}\text{×}\text{Temperature}}{\text{Volume}}$
