(a)

Interpretation Introduction

Interpretation:

From the phase diagram, phase that the substance found at room temperature and 1.0atm pressure has to be determined.

Concept introduction:

Under certain specific conditions, two states can coexist in equilibrium; can be represented in phase diagram.

The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.

(b)

Interpretation Introduction

Interpretation:

From the phase diagram, phase that the substance exists has to be identified.

Concept introduction:

Under certain specific conditions, two states can coexist in equilibrium; can be represented in phase diagram.

The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.

Interpretation Introduction

Interpretation:

According to the Phase diagram, the vapor pressure of the solid at 1220C has to be identified.

Concept introduction:
