Chapter 5, Problem 5.2P

(a)

Interpretation Introduction

Interpretation:

Whether the particles in a gas are farther apart or closer together in comparison to the particles in a liquid should be determined and answer should be used for the explanation of following observation:

Liquids are less compressible than gases.

Concept Introduction:

The characteristics of gases and liquids are:

1. Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
2. Liquid has more density in comparison to gas but less than solid.
3. Liquid has small compressibility in comparison to gas but larger than solid.
4. Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.

(b)

Interpretation Introduction

Interpretation:

The following observation should be explained.

The flow of gas is more freely in comparison to liquid.

Concept Introduction:

The characteristics of gases and liquids are:

1. Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
2. Liquid has more density in comparison to gas but less than solid.
3. Liquid has small compressibility in comparison to gas but larger than solid.
4. Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.

(c)

Interpretation Introduction

Interpretation:

The following observation should be explained.

All gaseous mixtures are solutions after stirring.

Concept Introduction:

The characteristics of gases and liquids are:

1. Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
2. Liquid has more density in comparison to gas but less than solid.
