Across
- 2. A measure of the average kinetic energy or the particles in a sample of matter
- 3. A characteristic of matter that depends on the amount of matter
- 5. The study of the transfer of energy as heat that accompanies chemical reactions and physical changes
- 9. Anything that has mass and takes up space
- 10. A substance made up of atoms of 2 or more different elements joined by chemical bonds that makes a new substance
- 11. A characteristic of matter that does not depend on the amount of matter
- 14. The energy transferred between samples of matter because of a difference in temperature
- 16. Change in the identity or type of matter
- 17. Absorbed/released energy, Bubbles, Color Change, Odor, Formation of a precipitate
- 18. Composed of dissimilar components and is not uniform
- 19. Change in the identity or type of matter stays the same,but the appearance changes
- 20. A combination of 2 or more substances that are not chemically combined
Down
- 1. A sample of matter either a single element or a single compound that has definite chemical and physical properties
- 4. A chemical reaction that causes the absorption of heat
- 6. Describes something that has a uniform structure or composition throughout
