Chapter 11, Problem 67SCQ

(a)

Interpretation Introduction

Interpretation: The appearance of the system when water is placed in a thick- walled glass tube whose internal volume is $50c{m}^3$ has to be identified.

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.

(b)

Interpretation Introduction

Interpretation: The pressure in the tube when water is placed in a thick- walled glass tube whose internal volume is $50c{m}^3$ has to be identified.

(c)

Interpretation Introduction

Interpretation: Volume of the liquid water in the tube has to be identified.

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.

Volume of liquid=$\frac{mass}{density}$

(d)

Interpretation Introduction

Interpretation:

Mass of water in the vapor state has to be calculated.

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.
