Chapter 8, Problem 8.52AP

Interpretation Introduction

Interpretation:

The definition for Charles' law and the variables which should be kept constant for the law to hold should be determined.

Concept Introduction:

Charles' law: States that volume is directly proportional to temperature when the gas is held at constant pressure and number of molecules.

$\begin{array}{l}\text{V}\propto \text{T}\\ \text{V}\text{=}\text{constant}\text{×}\text{T}\\ \frac{{\text{V}}_{\text{1}}}{{\text{T}}_{\text{1}}}\text{=}\frac{{\text{V}}_{\text{2}}}{{\text{T}}_{\text{2}}}\end{array}$

Temperature should be in kelvins.

The importance of law is that this gas law is valid only at constant pressure and number of molecules.
