Chapter 12.7, Problem 1RC

Interpretation Introduction

Interpretation:

The false statement should be identified.

Concept introduction:

All three phases of ${\text{CO}}_{\text{2}}$ exist simultaneously at the triple point.

${\text{CO}}_{\text{2}}$ forms a supercritical fluid at temperatures less than $31{}^{\text{o}}\text{C}$.

${\text{CO}}_{\text{2}}$ is a gas under normal conditions of temperature and pressure.

${\text{CO}}_{\text{2}}$ exists as a solid when the pressure is 4 atm and the temperature is more than $\text{-56}\text{.6}{}^{\text{o}}\text{C}$.
