Chapter 15, Problem 6CR

Interpretation Introduction

Interpretation:

The validation of the fact that the volume of a gas varies as the temperature of the sample changed is to be stated on the basis of Charles’s law. The difference between volume-temperature relationship and the volume-pressure relationship of Boyle’s law is to be stated. The two mathematical expressions of Charles’s law are to be shown. The reason as to why the pressure and amount of gas remain the same in Charles’s law is to be stated. The sketch of the general shape of a graph of volume versus temperature (at constant pressure) for an ideal gas is to be drawn.

Concept Introduction:

Avogadro was the scientist who described the relationship between the number of moles of gas and volume of a gas. An ideal gas equation is derived from the combination of Charles’s law, Boyle’s law and Avogadro law.

The general expression for an ideal gas is shown below.

$\text{P}\text{V}=\text{n}\text{R}\text{T}$

This expression exhibits that an ideal gas law relies on the temperature, pressure, volume and moles of gas.
