Chapter 11, Problem 11.66SP

Interpretation Introduction

Interpretation:

The phase diagram for krypton should be sketched. Whether krypton can be liquefied as room temperature or not should be determined.

Concept introduction:

Phase diagram is a graph that represents the solid phase, liquidphase, 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 coexistis 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 liquefication of gas. The highest temperatureat 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.
