Chapter 8 Vocab

3. The property of a liquid that describes how it pours.
6. The change from the gaseous state to the liquid state.
9. All matter is made up of tiny particles that are in constant motion.
15. The SI unit of pressure; one newton per square meter.
16. The state of matter having a definite volume and shape.
17. States that pressure applied to a fluid is transmitted unchanged throughout the fluid, the force is the same everywhere.
18. The state of matter that lacks definite shape or volume.
20. The high temperature state of matter in which atoms lose their electrons; high energy, electrically charged particles.
21. The temperature at which a material freezes.
23. The direct change of state from a solid to a gas or a gas to a solid.

1. The amount of force per unit area.
2. The energy needed to change a liquid to a gas.
4. The temperature at which a substance changes rapidly from a liquid to a gas.
5. The upward force of a fluid on an on an object in it.
7. States that the pressure in a fluid is high where its velocity is low; the pressure is low where the velocity is high.
8. A solid material having a regular repeating geometric form characteristic of a given compound or element.
10. The increase in volume of matter as the temperature goes up.
11. The change from the liquid to the gaseous state at the liquid surface.
12. The buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
13. States that if a sample of gas is kept at constant temperature, decreasing the volume will increase the pressure the gas exerts.
14. The temperature at which a substance changes from a solid to a liquid.
19. The energy necessary to change a solid to a liquid.
22. The state of matter having a constant volume but no definite shape.
