Question
Chapter 12, Problem 5E
Interpretation Introduction
Interpretation:
The boiling point, melting point, and intermolecular forces are to be defined.
Concept Introduction:
Liquids are composed of molecules that are mutually held by intermolecular forces of attraction.
These molecules are constantly moving within the liquid and possess certain amount of energy at any given temperature.
The state of the liquid can be altered by modifying the energies.
