- 2. a decision made after considering relevant facts and evidence
- 5. state of matter that keeps its volume, but takes the shape of its container. Particles have medium energy and move freely at medium speeds
- 6. change a change in matter in which a new substance is formed.
- 9. a pure substance that cannot be broken down by chemical or physical means
- 10. the amount of matter or "stuff" that is found inside an object
- 13. change a change in the form (size or shape) of an object
- 14. the measurement of how much mass of a substance is contained in a given volume
- 16. Table an arrangement tool of the known elements organized by properties
- 17. change a change in state of matter (ex: solid to liquid, liquid to gas, etc.)
- 19. vaporization of a liquid that occurs only on the surface of the liquid
- 20. state of matter that takes the shape and volume of the container it's in. Particles have high energy and move freely at high speeds.
- 21. smallest particle of an element.
- 24. Variable the only variable that is changed by the person conducting the experiment to explore its effect(s)
- 25. change in the physical state of matter from the liquid phase to the gas phase
- 27. Variables the variables in an experiment which are held constant
Down
- 1. two or more atoms that are chemically bonded.
- 3. the amount of space an object takes up
- 4. a physical change in which particles of a substance are separated by water particles
- 6. change in physical state of matter from the gas phase to the liquid phase
- 7. change in state from solid to liquid
- 8. change in the physical state of matter from the gas phase to the solid phase without passing through the liquid phase
- 11. Bonding Force that holds atoms together.
- 12. change in state from liquid to solid
- 15. anything that has mass and takes up space
- 18. the ability of a substance to dissolve
- 22. change in state from solid to gas without liquid phase.
- 23. Variable the variable that is measured to determine the results.
- 26. state of matter that keeps its shape and volume. Particles have low energy and vibrate slowly in place
