Across
  1. 3. Solids and liquids can be changed from one state to another by heating or cooling.
  2. 5. is a group of atoms cooled to within a hair of absolute zero
  3. 7. A material composed of two or more substances
  4. 9. which are zeros at the end of a number, are significant only if the number has a decimal point
  5. 11. has an indefinite shape and able to flow
  6. 12. Parts and composition of matter
  7. 14. Matter and the environment
  8. 15. liquid or solid to gas
  9. 17. which all numbers are significant
  10. 19. energy changes
  11. 24. is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid
  12. 25. some substances are attracted to a magnet field and can be "pulled" from a mixture
  13. 26. have characteristics common to metals as well as non-metals
  14. 27. is a common abbreviation for significant figures
  15. 28. Focuses on carbon-containing compounds
  16. 30. generally solids such as copper,iron,etc.
  17. 31. Heat involved in chemical processes
  18. 34. everything that takes up space and has mass
  19. 35. generally non lustrous; ex: Sulphur,nitrogen,etc.
  20. 38. A process that does not cause a substance to become a fundamentally different substance
  21. 39. sublimating material changes from a solid to a gas
  22. 40. is an effective method to separate mixtures comprised of two or more pure liquids
  23. 42. is a mixture in which the composition is not uniform throughout the mixture
  24. 44. Any characteristic that can be determined without changing the substance’s chemical identity
  25. 45. A substance that cannot be broken down into chemically simpler components
  26. 48. is essentially a physical method of separation in which the components of a mixture are separated by their distribution between two phases
  27. 49. is a mixture in which the composition is uniform throughout the mixture
  28. 50. Chemical interactions
  29. 51. Any characteristic that can be determined only by changing a substance’s molecular structure
