2. how hot or cold something is; the measure of the average kinetic energy of the particles in a substance
9. the process by which the molecules at the surface of a liquid absorb enough energy to change to a gas
10. a principle that describes the relationship between pressure and volume of a gas at constant temperature
12. a state of matter that has no definite shape or volume
13. the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together, causing the surface to act as if it has thin skin
15. a liquid's resistance to flowing
16. the total kinetic and potential energy of all the particles of an object
17. the change of state from a gas to a liquid

1. the temperature at which a liquid freezes
3. the force pushing on a surface divided by the area of that surface
4. the temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to a solid
5. a principle that describes the relationship between the temperature and volume of a gas at constant pressure
6. the change in state from a solid directly to a gas without passing through the liquid state
7. the change of state from liquid to a gas
8. a state of matter that has no definite shape but has a definite volume
11. a state of matter that has a definite shape and definite volume.
14. the temperature at which a liquid boils
