Chapter 10, Problem 165AP

Interpretation Introduction

Interpretation:

The air temperature and the percent decrease in oxygengas are to be calculated.

Concept introduction:

From the ideal gas equation, the relationship between density and molar mass can be deduced. This can be shown as

$d=\frac{PM}{RT}$

Here, M represents the molar mass of the gas, $R$ is the gas constant, $T$ is the temperature, $V$ is the volume, and $d$ is the density.

The ideal gas equation elaborates the physical properties of gases by relating the pressure, volume, temperature, and number of moles with each other with the help of four gas laws. This can be shown as

$PV=nRT$

Here, $n$ is the number of moles, $R$ is the gas constant, $T$ is the temperature, $V$ is the volume, and $P$ is the pressure.
