Chapter 7.1, Problem 7.4Q

Interpretation Introduction

Interpretation:

Among ${\text{H}}_{\text{2}}\text{O}(l)$ and ${\text{H}}_{\text{2}}\text{O}(g)$, the substance that has greatest entropy has to be identified and the reason has to be explained.

Concept Introduction:

Entropy can be said as the measure of randomness in a chemical system.  Entropy of a substance is symbolized as $S$.  If the chemical system is well ordered means the entropy will be low while the chemical system is disordered and random means then the entropy will be high.  In a general way it can be said that gases has high entropy while solids have low entropy.  This is because in solids, the particles are ordered and in gases they are disordered.
