Kinetic Particle Theory

Question 1

What is the Kinetic Particle Theory?

Answer 1

All matter is made up of tiny particles, and these particles are in constant, random motion

Question 2

Evaporation VS Boiling

Answer 2

Evaporation: Occurs only at surface of liquid, occurs at and below boiling point

Boiling: Occurs throughout liquid, occurs only at boiling point

Question 3

Arrangment of Solid Particles

Answer 3

Particles are very closely packed together in a orderly manner

Question 4

Movement of Solid Particles

Answer 4

Particles vibrate and rotate about their fixed positions

Question 5

Arrangement of Liquid Particles

Answer 5

Particles are closely packed together in a disorderly manner

Question 6

Movement of Liquid Particles

Answer 6

Particles move freely by sliding past one another

Question 7

Arrangement of Gas Particles

Answer 7

Particles are very far apart in a disorderly manner

Question 8

Movement of Gas Particles

Answer 8

Movement: particles move about in all directions at high speeds

Question 9

Describe the heating curve

Answer 9

A-B: Temperature rises, particles in solid state takes in heat, kinetic energy increases, particles vibrate faster in fixed positions
B-C: Temperature remains constant, particles gain enough energy to overcome the forces of attraction between particles, temperature constant as energy used for breaking forces of attraction, particles move about, solid to liquid
C-D: Temp rises, particles in liquid state takes in heat, kinetic energy increases, particles move about faster
D-E: Temp remains constant, particles gain enough energy to overcome the forces of attraction between particles, temp is constant as energy used for breaking forces of attraction, particles escape from liquid into surroundings, becomes a gas
E-F: Temp continues to increase as particles gain more heat and kinetic energy to move at higher speeds in all directions
