Chapter 5.5, Problem 5.1P

(a)

Interpretation Introduction

Interpretation:

The difference in the behaviour of a sample of gas from a sample of liquids when the sample is transferred from one container to a larger one is to be explained.

Concept introduction:

Gases have weak intramolecular forces of attraction in comparison to liquids. The weak intramolecular forces lead to very less attraction among the gaseous particles resulting in its free motion.

Liquids have stronger intramolecular forces of attraction than gases and this property of liquids make it highly fluid in nature.

(b)

Interpretation Introduction

Interpretation:

The difference in the behaviour of a sample of gas from a sample of liquids when the sample heated in an expandable container is to be explained.

Concept introduction:

Gases have weak intramolecular forces of attraction in comparison to liquids. The weak intramolecular forces lead to very less attraction among the gaseous particles resulting in its free motion.

Liquids have stronger intramolecular forces of attraction than gases and this property of liquids make it highly fluid in nature.

The volume of the gas is dependent on the temperature, as the temperature increases the volume increase.

(c)

Interpretation Introduction

Interpretation:

The difference in the behaviour of a sample of gas from a sample of liquids when the external force applied to the piston of an expandable container is to be explained.

Concept introduction:

Gases have weak intramolecular forces of attraction in comparison to liquids. The weak intramolecular forces lead to very less attraction among the gaseous particles resulting in its free motion.

Liquids have stronger intramolecular forces of attraction than gases and this property of liquids make it highly fluid in nature.

The volume of the gas is inversely proportional to the pressure, as the pressure increases the volume decrease.
