Chapter 1, Problem 42P

Interpretation Introduction

Interpretation:

The most stable state of substances at low temperatures should be identified.

Concept introduction:

There are 3 states of matter or a matter can exist in 3 states namely solid, liquid and gas. The state describes the shape and physical properties of matter.

The increasing order of space between the particles in matter existing as solid, liquid or gas is as follows:

Solid<Liquid<Gas.

Thus, particles of gases are in random motion.
