Chapter 12, Problem 102IAE

Interpretation Introduction

Interpretation:

The state/s of Cl₂ in the cylinder needs to be determined.

Concept introduction:

Critical point is the point at which both the liquid and the gas phase of a substance have the same density. At critical point, the liquid and vapor phases are indistinguishable. Just below the critical point, the surface separating the liquid from its vapor is observed. When a liquid is approaching its critical point, density of the liquid decreases and density of the vapor increases, surface tension of the liquid becomes zero. Critical temperature and pressure indicates the maximum temperature and pressure at which a liquid can exist. A gas can be liquefied only below its critical temperature.
