Chapter 12, Problem 11E

Interpretation Introduction

Interpretation:

The difference between evaporation at and below the boiling point of a liquid is to be explained.

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 these energies of the potent molecules.

Evaporation is defined as a process, in which the state of a substance changes from liquid to its vapor state below its boiling point. It is also called as vaporization. It varies with surface area, intermolecular forces and temperature. Evaporation is the endothermic process
