Across
- 4. particles are packed tightly together so they don't move much

- 7. whether the undergoes combustion or not
- 8. also called a solution
- 13. occurs when a gas transforms directly into a solid
- 18. a process of separating the components of a suspension
- 21. space occupied by a substance
- 25. whether it will break into charged particles when in solution with water or not
- 26. determined when a quantitative value is relative close to the true value
- 29. composition varies from one position to another within the sample
- 30. weight of a object
- 32. consist of a dispersed phase or the substance dissolved or scattered and a dispersing medium or the substance in which the dispersed phase is spread
- 38. the ratio of the mass of an object to the volume it occupies
- 40. The study of the chemistry of matter and the development of tools to measure properties of matter
- 41. The study of carbon and its compounds
- 42. this makes use of a magnet which exerts magnetic force to attract metallic particles and sets them apart from a certain mixture
- 43. The branch of chemistry that applies physics to the study of chemistry, which commonly includes the applications of thermodynamics and quantum mechanics to chemistry
- 46. The study of compounds not covered by organic chemistry
- 47. using centrifugal force to separate the mixture
- 48. process of simplifying a very large number
- 50. composed of two or more substance combined physically in variable proportion
Down
- 1. whether the material is more active or less active then other members of its chemical family
- 2. consist of coarse particle which are visible to the naked eye
- 3. physical properties, those that can be affected by size and amount of samples
- 5. a pure substance containing two or more kind s of atom chemically combined in a definite proportion by mass
- 9. a matter that has a definite composition and distinct properties
- 10. a process of separating a homogeneous mixture composed of to substance with different boiling points
- 11. the consistency of the result
- 12. the conversion of a liquid to a gas and can occur through either evaporation or boiling
- 14. When a solid is converted directly into a gas without going through a liquid phase
- 15. the solid particles are allowed to settle first at the bottom and later, the liquid which is called supernatant is poured into another container leaving behind the solid particles
- 16. occurs when a gas loses energy and comes together to form a liquid
- 17. the particles are more loosely packed than in a solid and are able to flow around each other
- 19. the dissolved substance
- 20. whether it react with acid, base and gasses or not
- 22. When the substance reaches a cool enough temperature at a certain pressure, the freezing point, the liquid becomes a solid
- 23. The study of chemical processes that occur inside of living organisms
- 24. the simplest form of matter since it is composed of only one kind of atom
- 27. how cold or hot an object
- 28. When the substance reaches a certain combination of temperature and pressure, its melting point, the solid will begin to melt and turn into a liquid.
- 31. whether substance can be decomposed or not
- 33. the ability of a substance to react other substance
- 34. another method of separating complex mixture
- 35. are those that can be measured and observed without changing the composition of the substance
- 36. determined when a quantitative value is relative close to the true value
- 37. the dissolving medium
- 39. the study of matter and chemical reaction between substance
- 44. physical properties, does not depend on the size or amount of the sample
- 45. whether the substance can damage an organism or not
- 49. the particles have a great deal of space between them and have high kinetic energy
