Chapter 7, Problem 7.57P

Interpretation Introduction

Interpretation:

The new volume of the balloon is to be determined when it is contains 2.2 L of gas at $25°C$ temperature which is cooled to $-78°C$.

Concept introduction:

According to Charles's law, the volume of gas is directly proportional to the Kelvin temperature of the gas at constant pressure. This relation is represented as −

  $V\propto T$

Or,

  $V_2=\frac{V_1{T}_2}{T_1}$

Where, V₁ is initial volume, V₂ is final volume, T₁ is initial temperature and T₂ is final temperature.
