kinetic theory

2. a liquids resistance to flow is known as this
6. the uneven forces acting on the particles on the surface of a liquid are called this
10. the things that make up all types of matter
12. the average kinetic energy of the individual particles is called this
14. a state of matter that has definite volume but no definite shape
18. the particles in this solid are found in random arrangement
19. the change from a solid state to a liquid state
20. the changing state of matter is called this

1. is equal to the force exerted on a surface divided by the total area
3. the particles in this solid are arranged in a repeating three dimentional pattern called a crystal
4. the particles in this state are much farther apart then in other states
5. the movement of thermal energy from a substance at a higher temperature to one at a lower temperature is called this
7. anything that takes up space and has mass
8. the change from a liquid state to a solid state is called this
9. the change from a liquid to a gas
11. this is a measure of the amount of energy required to raise 1 g of a substance 1 Celsius
13. is the change from a gaseous state to a liquid state
15. the change from a solid to a gas state
16. the hardest state of matter
17. the total kinetic and potential energy of all the particles in a sample of matter is called this
