Chapter 11, Problem 127E

Interpretation Introduction

Interpretation:

The expected volume of balloon is to be determined upon cooling and the difference between observed volume and calculated volume is to be explained.

Concept Introduction:

Charles’s law states that volume is directly proportional to the temperature. It can be expressed as:

$V\propto T$

According to the Charles’s law relation between $V_1,V_2,T_1$ and $T_2$ is:

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Air contains about $20\%$ oxygen.

The freezing point of oxygen $\left({\text{O}}_{\text{2}}\right)$ is ${\text{-183}}^{\text{°}}\text{C}$.
