Chapter 11, Problem 11.137QP

(a)

Interpretation Introduction

Interpretation:

Using phase diagram for Carbon dioxide ${\text{(CO}}_{\text{2}}\text{)}$,

• At room temperature, the expectation to see the cylinder if it were transparent has to be explained.
• The expectation of gauge to behave as we carry on using ${\text{CO}}_{\text{2}}$ from the cylinder until we can no longer obtain any ${\text{CO}}_{\text{2}}$.  This is to be explained.

Concept introduction:

Phase diagram: Phase diagram is a graphical representation to review the conditions under which varies states of a substance is constant.

Triple point: A point at which three phases of a substance meets together.

Critical point: The critical point is end point of the phase equilibrium curve in phase diagram.
