Chapter 1, Problem 1.84P

(a)

Interpretation Introduction

Interpretation:

The change that shows physical change is to be determined.

Concept introduction:

The change that takes place only in state or appearance and not in the composition is known as physical change. The atoms or the molecules of a substance do not change their identity when a substance undergoes a physical change. The change accompanied by the change in the physical properties only is classified as physical change. The substance remains the same before and after the change. For example, the melting of ice is a physical change.

Ice(water)liquid(water)

The change that takes place in the composition is known as chemical change. The atoms or the molecules of the substance rearrange and transformed into a new substance. For example, the burning of paper is a chemical change.

Interpretation Introduction

Interpretation:

The change that results in a change in state is to be determined.

Concept introduction:

The matter is classified as solids, liquids, and gases on the basis of state that depends on the physical form of matter.

In solids, the atoms and molecules have fixed positions and are closely packed to each other. The examples of matter that are solid are ice and diamond. In liquids, atoms and molecules are also closely packed to each other but they can move over each other. The examples of matter that are liquid are water and alcohol. In gases, the atoms and molecules have very large space between them and can easily move over each other hence gases are compressible. The examples of matter that are gases are nitrogen and carbon dioxide.
