Chapter 15, Problem 9CR

Interpretation Introduction

Interpretation:

The meaning of an ideal gas is to be stated. The reason as to why the ideal gas law $\left(\text{PV=nRT}\right)$ is actually a combination of Boyle’s, Charles’s, and Avogadro’s gas laws is to be explained. The numerical value and the specific units of the universal gas constant, $\text{R}$ are to be stated. The reason as to why the close attention to units is important when ideal gas law calculations are done is to be stated.

Concept Introduction:

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.

$\text{PV=nRT}$

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