States of Matter

5. the amount of space a substance occupies
6. state of matter that has a definite volume, but no definite shape
9. physical change of a liquid to a solid by the removal of energy as heat or increasing pressure
10. state of matter that has neither a definite volume nor shape
14. physical change from a liquid to gas by addition of energy as heat or decreasing pressure
15. physical change from a gas to a liquid by the removal of energy as heat or increasing pressure
17. physical change from gas to solid by removal of energy as heat or increasing pressure
18. anything that has mass and takes up space
19. temperature at which bubbles form inside the liquid
20. the force exerted by the substance per unit area on another substance

1. physical change from a solid to a gas without passing through the intermediate liquid phase
2. temperature at which the solid melts to become a liquid
3. particular temperature and pressure at which the solid, liquid, and gaseous phase of a substance are at equilibrium
4. a state of matter that has a fixed volume and shape
7. changes from one state of matter to another state of matter without a change in chemical composition
8. a measure of the average kinetic energy of the particles in an object
11. one of the principal conditions in which matter exists-solid, liquid, or gas
12. graphical representation of the physical states of matter under different conditions of temperature and pressure
13. a measure of the amount of matter in an object
16. physical change of a solid to liquid by addition of energy as heat or decreasing pressure
