Chapter 11.4, Problem 6PPA

Interpretation Introduction

Interpretation:

The volume of the balloon when it has risen to an altitude has to be calculated.

Concept introduction:

The combined gas law is a gas law that combines all gases law.  Charles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  Finally, Gay-Lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.

For this problem will be the combined gas law equation, which looks like this

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

For the reason that V is constant, the above equation reduces to

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