Chapter 16, Problem 102E

Interpretation Introduction

Interpretation: The phase diagram of bromine ${\text{Br}}_{\text{2}}$ needs to be explained and the following points needs to be identified.

• The order of 3 phases from least dense to most dense.
• Stable phase of bromine ${\text{Br}}_{\text{2}}$ at room temperature and 1 atm
• Temperature at which liquid bromine ${\text{Br}}_{\text{2}}$ never exist
• Phase change that occurs as the temperature of a sample of bromine ${\text{Br}}_{\text{2}}$at 0.10 atm is increases from -50 °C to 200°C.

Concept Introduction:

The conversion of solid to liquid and gas involves the change in temperature that can display in heat curve.

The heating -cooling curve is the curve of temperature v/s time that interpret the change in the states of matter with increase in temperature.

Freezing point is the temperature at which the solid state converts to liquid state or vice-versa. Boiling point is the temperature at which the liquid and gas state reach to an equilibrium hence after this temperature, both states must be in equilibrium.
