Chapter 8.1, Problem 8.2QAP

Interpretation Introduction

(a)

Interpretation:

Pressurised can on coming in contact with fire expodes should be identified.

Concept introduction:

Kinetic theory explains the fact:

1. Movement of gaseous particles occur fastly at higher temperature.
2. compression of gas can be easily dealt in comparison to solid or liquid
3. The particle of gases are very small and is far from each other.

The pressure is direct propotional to temperature as follows:

PV = n R T

The pressure increases on increasing the temperature while it decreases on decreasing the temperature.

Interpretation Introduction

(b)

Interpretation:

Hot air balloon rise up should be identified.

Concept introduction:

Kinetic theory explains the fact:

1. Movement of gaseous particles occur fastly at higher temperature.
2. compression of gas can be easily dealt in comparison to solid or liquid
3. The particle of gases are very small and is far from each other.

The density of gases are lower than liquid and solid.

Interpretation Introduction

(c)

Interpretation:

Smell of an onion can be smelled from far should be identified.
