- 3. The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first
- 5. The phase change in which a substance changes from a liquid into a gas
- 8. The phase change in which a substance changes from a gas or vapor to a liquid
- 9. The energy an object has due to its motion
- 12. State of matter in which a material has a definite volume but not a definite shape
- 13. States that the volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles of the gas are constant
- 14. This happens if water is in a closed container and the pressure caused by the collisions of the water vapor and the walls of the container
- 16. States that volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant
- 18. The amount of energy absorbed by a substance as it melts
- 19. A change in which the system absorbs energy from its surroundings
