Chapter 12.3, Problem 18SSC

Interpretation Introduction

Interpretation: The arrangements of atoms in solids and liquids must be contrasted.

Concept Introduction:

Solids have stronger intermolecular forces and liquids have moderate intermolecular forces.

Answer to Problem 18SSC

The arrangement of atoms in solid is very close as compared to liquid.

Explanation of Solution

As an intermolecular force in solid is strongest among solids, liquids and gases, so the atoms are closer in solids. Those atoms are tightly packed in the sample. On the other hand, liquids have moderate intermolecular forces that are stronger than gases but weaker than solids. So, arrangements of atoms are less close as compared to solids but more closer as compared to gases.

Conclusion

Solids have a closer atomic arrangement as compared to liquids.
