States of Matter

5. The energy an object has due to its motion.
6. The energy a substance must absorb in order to change from a solid to a liquid.
9. The phase change in which a substance changes from a gas or vapor to a liquid.
12. The result of a force distributed over an area.
13. The phase change in which a gas or vapor changes directly into a solid without first changing into a liquid.
16. The phase change in which a substance changes from a liquid into a gas.
17. The state of matter in which materials have a definite shape and a definite volume.
18. The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first.
19. The state of matter in which materials have neither a definite shape nor a definite volume.

1. The state of matter in which a material has definite volume but not a definite shape.
2. The inverse variation of the volume of a gas with its pressue if the temperature and the number of particles are constant.
3. A reversible physical change that occurs when a substance changes from one state of matter to another.
4. The energy a substance must absorb in order to change from a liquid to a gas.
7. The pressure caused by the collisions of particles in a vapor with the walls of a container.
8. A temperature of 0 kelvins.
10. The process that changes a substance from a liquid to a gas at temperature below the substance's boiling point.
11. A description of a change in which a system absorbs energy from its surroundings.
14. The direct proportion of the volume of a gas to its temperature (in kelvins) if the pressure and the number of particles of the gas are constant.
15. A description of a change in which a system releases energy to its surroundings.
