Chapter 11, Problem 11.63SP

Interpretation Introduction

Interpretation:

The initial and final phase of oxygen should be identified.

Concept introduction:

Phase diagram is a graph that represents the solid phase, liquid phase, and gaseous phase of one substance or mixture of substance under different conditions of temperature and pressure.

The temperature and pressure on a phase diagram at which gas, liquid, and solid phases coexist is called triple point. The temperature and pressure in the phase diagram at which substance is lies between liquid-gas phases is called critical point. The temperature and pressure at which liquid or gas is neither a true liquid nor a true gas is called supercritical point.

The conversion factor to convert Kelvin to $°\text{C}$ is as follows:

$T\left(°\text{C}\right)=T\left(\text{K}\right)-273$

The conversion factor to convert $\text{mmHg}$ to $\text{atm}$ is, $1\text{ atm}=760\text{}\text{mmHg}$

The conversion of a gas into a liquid state by change in temperature, pressure, and volume is termed as liquefaction of gas. The highest temperature at which gas changes into liquid is termed as critical temperature. The minimum pressure that liquefies gas at its critical temperature is termed as critical pressure.
