Chapter 14.3, Problem 36LC

Interpretation Introduction

Interpretation: To explain “No gas exhibits ideal behaviors at all temperatures and pressure.

Concept Introduction: A huge number of microscopic level particles, including atoms and molecules, are used in the kinetic theory of gases, a conceptual model, to characterize the molecular makeup of the gas.

Answer to Problem 36LC

According to the kinetic hypothesis, an ideal gas occupies no space since all matter consists of tiny moving pieces. Every material occupies space.

Explanation of Solution

According to the kinetic hypothesis, an ideal gas occupies no space since all matter consists of tiny moving pieces. Every material occupies space.

At higher temperatures and lower pressures, a gas typically behaves more similar to an ideal gas because the potential energy from intermolecular forces is less important compared to the kinetic energy of the particles and even the size of the molecules is less significant, especially in comparison to the void space between them.
