Textbook Problem

Make a drawing, based on the kinetic-molecular theory and the ideas about atoms and molecules presented in this chapter, of the arrangement of particles in each of the cases listed here. For each case, draw 10 particles of each substance. It is acceptable for your diagram to be two dimensional. Represent each atom as a circle, and distinguish each different kind of atom by shading.

(a) a homogeneous mixture of water vapor and helium gas (which consists of helium atoms)

(b) a heterogeneous mixture consisting of liquid water and solid aluminum; show a region of the sample that includes both substances

(c) a sample of brass (which is a homogeneous solid mixture of copper and zinc)

(a)

Interpretation Introduction

Interpretation:

The diagram for given states of matters based on Kinetic-molecular theory has to be drawn.

Concept Introduction:

Kinetic-molecular theory:

It helps to interpret the properties of solids, liquids, and gases.  The higher the temperature, the faster the particles move.  The energy of motion of the particles acts to overcome the forces of attraction between particles.

Explanation

In homogeneous mixture (both are gas phase), water vapor and helium particles are loosely arranged and have no contact with neighbors.  The net force of attraction between the gases is small.  The grey color represent balls represent the oxygen atoms and the orange...
