Chapter 11, Problem 11.63QP

Interpretation Introduction

Interpretation:

The ideal gas line of these gases has a pressure at which the assumption of ideal behaviour has to be explained.

Concept Introduction:

• The volume engaged by gas molecules is negligibly small as compared to the volume engaged by the gas.
• The forces of magnetism among gas molecules are negligible.
• The first hypothesis is valid only at low pressures and high temperature, when the volume engaged by the gas molecules is negligible as compared to the total volume of the gas.  Except at low temperature or at high pressure, the molecules being in compressible the volumes of molecules are no more insignificant as compared to the total volume of the gas.
