Chapter 9, Problem 65QP

Interpretation Introduction

Interpretation:

The final volume of the $O_2$ gas at STP, that is pumped into tank is to be determined.

Concept Introduction:

Combined gas law states that the pressure and volume of a gas are directly proportional to the temperature if the number of molecules of gas are constant. When the temperature of a gas increases, the pressure and the volume of a fixed also increase and vice versa.

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

Here $P_1$ , $T_1$ , $V_1$ represent the pressure ,temperature and volume of gas in the initial state. $P_2$ , $T_2$ , $V_2$ represent the pressure, temperature, and volume of gas in the final state.
