1) STATES OF MATTER

Question 1

Describe the particle separation of solids

Answer 1

Particles are very close together

Question 2

Describe the particle arrangement in solids

Answer 2

Particles are arranged in a fixed, regular pattern (lattice structure)

Question 3

Describe the particle motion in solids

Answer 3

Particles vibrate about their fixed positions

Question 4

Describe the particle separation in liquids

Answer 4

Particles are moderately close

Question 5

Describe the particle arrangement in liquids

Answer 5

Particles are arranged in a random manner

Question 6

Describe the particle motion in liquids

Answer 6

Particles can move freely past each other, allowing the liquid to flow

Question 7

Describe the particle separation in gases

Answer 7

Particles are far apart

Question 8

Describe the particle arrangement in gases

Answer 8

Particles are arranged in a random and scattered manner

Question 9

Describe the particle motion in gases

Answer 9

Particles move rapidly and freely in all directions.

Question 10

Define diffusion

Answer 10

The net movement on particles from an area of high concentration to an area of low concentration until the particles are evenly spread out.

Question 11

What does the kinetic particle theory state

Answer 11

All matter is made up of tiny particles (atoms or molecules) that are in constant motion.

Question 12

Factors that affect diffusion

Answer 12

1) Temperature
2) Relative molecular mass

Question 13

How does the kinetic particle theory relate with diffusion

Answer 13

Diffusion occurs because particles are in constant, random motion due to their kinetic energy.
