Chapter 7, Problem 7.3EP

(a)

Interpretation Introduction

Interpretation:

By using kinetic molecular theory, what type of energy is related to cohesive forces has to be answered.

Concept Introduction:

Kinetic Molecular Theory of matter says about the way of matter can change among its phases of solid, liquid, and gas.  The basic idea of this theory is about the particles (atoms, molecules, or ions) present in a substance has constant motion and are attracted or repelled by each other. The kinetic molecular theory of matter provides five statements which explain the physical behavior of the three states of matter (solids, liquids, and gases) and they are summarized as follows,

1. 1. Matter is composed of tiny particles (atoms, molecules, or ions) that have definite and characteristic sizes that do not change.
2. 2. The particles are in constant random motion and therefore possess kinetic energy.
3. 3. The particles interact with one another through attractions and repulsions and therefore possess potential energy.
4. 4. The kinetic energy (velocity) of the particles increases as the temperature is increased.
5. 5. The particles in a system transfer energy to each other through elastic collisions.
