Chapter 14, Problem 14A.12P

Interpretation Introduction

Interpretation:

The refractive index depends on the pressure as $n_{\text{r}}=1+\text{constant}\times p$ has to be shown.  The constant of proportionality for the relation has to be determined.  The polarizability volume of a molecule in terms of the refractive index of a gaseous sample has to be stated.

Concept introduction:

The dipole forces are attractive forces between two permanent dipoles.  The interaction is between the positive end of one polar molecule and the negative end of another polar molecule.  The induced dipole interaction occurs when an ion or a dipole induces a temporary dipole in an atom or a molecule with no dipole.  The induced dipole forces are the attraction forces between molecules having temporary dipoles.
