1. Kinetic Particle Theory

13. 3 states of matter (Difference) Property Solid Liquid Gas Volume Fixed Fixed Not Fixed Shape Fixed Not Fixed Not Fixed Compressibility Not compressible Not compressible compressible Density Very Dense Dense Not dense Packing and arrangement between particles Closely packed in an orderly arrangement Closely packed in an disorderly arrangement Far apart in random arrangement.

14. 3 states of matter (Difference) Property Solid Liquid Gas Forces of Attraction between particles Very strong forces of attraction between particles Strong forces of attraction between particles Negligible forces of attraction between particles Motion of particles Vibrate about a fixed position Slide and roll pass each other Move about randomly at high speed Energy of particles Least energy Most energy

17. The Solid State

18. Arrangement of particles (In a solid) high densities cannot be compressed straight edges Arrangement and movement of particles Properties of solids The particles are closely packed together , with little empty space between them. Solids have and . The particles are in an orderly arrangement . Solid crystals have flat faces, and sharp points

19. Arrangement of particles (In a solid) fixed cannot The particles are held together by strong forces of attraction between them, in fixed positions. Solids have shapes and be compressed. The particles can only vibrate about their fixed positions. Arrangement and movement of particles Properties of solids

20. The Liquid State

21. Arrangement of particles (In a Liquid) moderately high cannot no Arrangement and movement of particles Properties of Liquids The particles are closely packed together (but slightly further apart than those in solid), with little empty space between them. Liquids have densities and be compressed . The particles are in a disorderly arrangement. Liquids have fixed shapes .

22. Arrangement of particles (In a Liquid) cannot flow shape Arrangement and movement of particles Properties of Liquids The particles are held together by strong forces of attraction between them (but slightly weaker than the forces in a solid) Liquids be compressed . The particles can move past one another and throughout the liquid . Liquids can and take the of their containers.

23. The Gaseous State

24. Arrangement of particles (In a Gas) low easily no Arrangement and movement of particles Properties of Gas The particles are far apart , with a lot of empty space between them. Gases have densities and can be compressed. The particles are in a random arrangement . Gases have shapes .

25. Arrangement of particles (In a Gas) easily no definite definite shape Arrangement and movement of particles Properties of Gas There are no (negligible) forces of attraction between the particles. Gases can be compressed , hence volume . The particles are free to move randomly in all directions, at high speed . Gases have no shapes and take the of their containers .
