Chapter 6, Problem 15E

Interpretation Introduction

Interpretation:

The temperature of the He gas filled in the balloon at higher altitude needs to be determined.

Concept introduction:

The combine gas law states that at two conditions of pressure, volume and temperature, the ideal gas equation can be written as:

$\frac{P1\times V1}{T1}=\frac{P2\times V2}{T2}$

Here, $P_1$ is initial pressure, $P_2$ is final pressure,

$V_1$ is initial volume, $V_2$ is final volume, $T_1$ is initial temperature and $T_2$ is final temperature.
