Chapter 13.2, Problem 11LC

Interpretation Introduction

Interpretation:

The evaporation of liquid molecules in terms of kinetic energy is to be explained.

Concept Introduction :

The three states of matter are solid, liquid, and gas. It is feasible to understand why they have different qualities by looking at the way their particles are arranged.

Answer to Problem 11LC

Kinetic energy increases with an increase in temperature which tends to increase the molecular speed.

Explanation of Solution

In contrast to solids, particles are less tightly packed in liquids. Liquids take on that shape when maintained in a container. Compression is challenging in liquids because there is less room for particle mobility. Although liquids have a fixed volume, their shapes are not.

The average kinetic energy of a liquid's particles rises as it warms. As more and more molecules can reach the liquid's surface and enter the vapor phase, the rate of evaporation accelerates. The liquid eventually reaches a point where all the molecules have enough kinetic energy to evaporate.
