Chapter 11.3, Problem 11.4E

(a)

Interpretation Introduction

Interpretation:

Liquefaction of the following gases has to be described.

Methyl chloride ${\text{CH}}_{\text{3}}\text{Cl}$(critical point is $\text{144°C}$, $\text{66 atm}$)

Concept introduction:

Liquefaction: It is the process that produces a liquid from a gas or solid that produces a non-liquid state which performs on agreement with fluid subtleties.

Liquid air is cooled to very low temperature.  To protect them, they retained in a vacuum system with insulated flask.  These kinds of gases called permanent gases.  They cannot be liquefied by compression at room temperature.

(b)

Interpretation Introduction

Interpretation:

Liquefaction of the following gases has to be described.

Oxygen (critical point is $\text{-119°C}$, $\text{50 atm}$)
