Chapter 15, Problem 20CR

Interpretation Introduction

Interpretation:

The reason as to why the process of vaporization requires an input of energy is to be stated. The reason as to why it is important that water has a large heat of vaporization is to be stated. The definition of condensation is to be stated. The explanation corresponding to the given statement that is the process of vaporization and condensation represent equilibrium in a closed container is to be stated. The equilibrium vapor pressure of a liquid is to be defined. An explanation for the increase of pressure in a closed container is to be stated. An experiment that demonstrates vapor pressure and aids in measuring the magnitude of heat pressure is to be described. An explanation for the magnitude of liquid’s vapor pressure related to the intermolecular forces in the liquid is to be stated.

Concept Introduction:

There are two types of forces that exist between the molecules. These forces are intermolecular and intramolecular forces. Intermolecular forces are always present between the two or more molecules, whereas intramolecular forces are present within the same molecule.
