Chapter 5, Problem 5.21PAE

Interpretation Introduction

Interpretation:

The behavior of gases that is responsible that a Mylar balloon that is bought in the winter months in colder places losses its shape when it is outside and recovers its shape when it is inside has to be explained.

Concept Introduction:

• An ideal gas has is a hypothetical gas that is formed by a few molecules so that, its density is low, and the intermolecular forces are null. The model of gas facilitates mathematical calculations to study gases.
• The ideal gas law relates the pressure, the temperature and the volume when the gas passes from a state 1 to a state 2 and the number of moles remains constant. This law can be expressed in the following way,

$\frac{{\text{P}}_{\text{1}}{\text{V}}_{\text{1}}}{{\text{T}}_{\text{1}}}=\frac{{\text{P}}_2{\text{V}}_2}{{\text{T}}_2}$

Where P₁ and P₂ are the gas pressure in the state 1 and 2, V₁ and V₂ are the gas volume in the s

state 1 and 2 and T₁ and T₂ are the gas temperature in the state 1 and 2.
