Chapter 10, Problem 10.90QP

(a)

Interpretation Introduction

Interpretation: The phase or phases of water that exist under the given conditions is to be stated.

Concept introduction: Triple point is a point present in the pressure- temperature graph. It is defined as the point at which all the three phases of a substance coexist in equilibrium with each other at a time.

Critical point is a point present in the pressure- temperature graph where two phases that is liquid and gas coexist in equilibrium. At this point gaseous and liquid states are indistinguishable from each other.

To determine: The phase or phases of water that exist at $\text{2}\text{.0}\text{atm}$ of pressure and $\text{50}\text{°C}$ of temperature.

(b)

Interpretation Introduction

To determine: The phase or phases of water that exist at $\text{0}\text{.10}\text{atm}$ of pressure and $\text{300}\text{°C}$ of temperature.

(c)

Interpretation Introduction

To determine: The phase or phases of water that exist at $\text{1}\text{atm}$ of pressure and $\text{0}\text{°C}$ of temperature.
