Chapter 9, Problem 125QP

Interpretation Introduction

Interpretation:

The final temperature of the balloon is to be determined.

Concept Introduction:

Gay Lussac’s law gives a relation between pressure and temperature at fixed volume. The pressure of a gas is directly proportional to the temperature of the gas when the volume of the gas is constant. When the pressure of the gas is increased, the temperature of the gas also increases at fixed volume.

$\begin{array}{c}P\propto T\\ \frac{P_1}{T_1}=\frac{P_2}{T_2}\end{array}$
