Chapter 13, Problem 32A

Interpretation Introduction

Interpretation: The statements which are the characteristics of gases are to be selected.

Concept introduction:

The three states of matter are solid, liquid, and gas. It is feasible to understand why they have different qualities by looking at the way their particles are arranged.

Answer to Problem 32A

Statements (a), (b), (c), and (e) are correct.

Explanation of Solution

A state of matter known as gas lacks both a definite shape and a fixed volume. There is a lot of vacant space between particles since they have a lot of kinetic energy and no attractive forces between them. Since a lot of spaces are present between gaseous particles, thus, they are compressible.

Hence, statement (e) is correct.

Since the molecules in gases are relatively loosely packed, they have large intermolecular gaps, and as a result, they take up the volume in which they are filled.

Hence, statement (a) is correct.

Gases exert pressure by

Anything with mass and space is considered matter. Since gas is one of the states of matter, it has mass as well.

Hence, statement (c) is correct.

The collisions of gaseous particles with the wall exert pressure.

Hence, statement (b) is correct.

Conclusion

Reason for incorrect statement:

Pressure depends upon the temperature as per the ideal gas equation. Thus, option (d) is incorrect.
