Chapter 9, Problem 79QP

Interpretation Introduction

Interpretation:

The final volume of the ${\text{O}}_2$ gas at STP is to be determined.

Concept Introduction:

Combined gas law states that the pressure $\left(P\right)$ and volume of the gas $\left(V\right)$ is directly proportional to the temperature $\left(T\right)$ when the amount of gas is fixed. When the temperature of gas increases, the pressure of gas and volume of a fixed amount of gas also increases and vice versa.

$\begin{array}{c}PV\propto T\\ \frac{PV}{T}=k\\ \frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}\mathrm{......}\left(1\right)\end{array}$
