Chapter 10, Problem 4CE

Interpretation Introduction

Interpretation:

Whether the volume of the balloon increases or decreases if air in an elastic balloon cools from $2\text{5}{}^{\text{ο}}\text{C}$ to $20{}^{\text{ο}}\text{C}$ is to be predicted.

Concept introduction:

Charles reveals the temperature effect on the volume of a gas. According to the Charles law, the volume of gas shows direct relation with the temperature in Kelvin at a constant pressure. Mathematically, it is expressed, as shown below.

$\begin{array}{l}V\alpha T\\ V=kT\end{array}$

Here, $k$ is the proportionality constant.
