Chapter 4, Problem 4G.1E

(a)

Interpretation Introduction

Interpretation:

The entropy of a solid nanostructure made of 64 molecules in which the molecules are aligned in the same direction has to be calculated.

Concept Introduction:

Boltzmann Formula:

The Boltzmann formula for the entropy is,

  $\text{S=k}\text{lnW}$

Here, S is the entropy

  k is Boltzmann’s constant $\left(\text{1}{\text{.381×10}}^{\text{-23}}\text{J}\cdot {\text{K}}^{\text{-1}}\right)$

    W is called as microstates

(b)

Interpretation Introduction

Interpretation:

The entropy of a solid nanostructure made of 64 molecules in which the molecules can lie in any one of four orientations has to be calculated.
