Across
- 3. fluid state of matter made of extremely high-temperature, ionized particles. ex: stars
- 5. rigid state of matter composed of molecules in a fixed arrangement; definite shape and volume ex: ice, desk, book, chair
- 7. fluid state of matter in which the particles are so far apart and move so fast that they have almost no attraction for each other; no fixed shape or volume
- 8. the change of state from a gas directly to a solid without becoming a liquid first
- 10. force of gravitational attraction for an object's mass
- 14. ANY change of state from a liquid to a gas
- 16. material made of just one kind of element or compound
- 18. anything that occupies space and has mass
- 19. the change of state from a liquid to a gas below the boiling point of the liquid
- 20. force of attraction between any two objects originating in the matter they contain
Down
- 1. the change of state from a liquid to a gas at the liquid's boiling point
- 2. the change of state from a gas to a liquid by cooling
- 4. fluid state of matter in which the particles are close together but can move freely about, ex water, molasses, soda, etc.
- 5. physical form of matter described by its rigidity or fluidity, its ability to hold its shape and how definite its volume is
- 6. the change of state from a solid directly to a gas without becoming a liquid first
- 9. hotness or coldness of a substance stated in degrees
- 11. two or more substances mixed together but not chemically combined
- 12. measure of the amount of matter an object contains
- 13. the change of state from a liquid to a solid by cooling
- 15. the amount of space a sample of matter occupies
- 17. the change of state from a solid to a liquid by warming
