- 11. the dissolved substance
- 12. it is the amount of space occupied by a substance
- 15. it is consist of coarse particles which are visible to the naked eye
- 18. a process where placing the ice at room temperature turns the ice back into liquid state
- 19. is the simplest form of matter since it is composed of only one kind of atom
- 21. the dissolving medium
- 24. it is determined when a certain quantitative value is relatively close to the "true" value
- 26. the shape and the volume are not definite and the particles are far apart from each other
- 27. it is the consistency of the result
- 28. the symbol is kg and the quantity is mass
- 29. the smallest particle of an element
- 31. liquid that passes through the strainer
- 33. it tells how hot or cold an object is
- 34. it is consist of a dispersed phase or the substance that is dissolved or scattered and a dispersing medium or the substance in which the dispersed phase is spread
- 37. in _____ and subtraction, the answer must have the same number of decimal places as the measured number with the least number of decimal places
- 38. the substance which remains in the strainer
- 39. it is the ratio of the mass of an object to the volume it occupies
- 40. ______ separation is the process of separating elemental metals from other particles of the mixture
- 42. a mixture whose composition varies from one position to another within the sample
- 44. it can be separated into simpler substances, but only through chemical means

Down
- 1. it occurs when gas is converted to solid
- 3. the symbol is K and the quantity is temperature
- 4. composed of two or more substances combined physically in variable proportions
- 6. it occurs when solid is converted to gas by the addition of heat
- 8. it is also called as intensive property and it does not depend on the size or amount of the sample
- 9. a process where the mixture is poured into a special tube in the centrifuge apparatus, and is allowed to spin using centrifugal force
- 11. whether the substance can be easily decomposed or not
- 13. a study of chemical processes occurring in living organisms
- 14. a process where if it is heated, the liquid state changes to gas; the molecules move very fast and take up space everywhere
- 16. it is the liquid that is poured into another container leaving behind the solid particle
- 17. are definite and the particles are very close to each other
- 20. the study of matter and the chemical reactions between substances
- 22. the quantity of matter in the object
- 23. a mixture, also called a solution, is relatively uniform in composition; every portion of the mixture is like every other portion
- 25. whether the substance undergoes combustion or not
- 30. whether the substance can damage an organism or not
- 31. a process of separating the components of a suspension
- 32. a process where the solid particles are allowed to settle first at the bottom and later the liquid is poured into another container leaving behind the solid particle
- 35. anything ththe shape and the volume at has mass and occupies space
- 36. another method of separating complex mixtures, the separation depends upon the solubility of each component in the solvent
- 40. in _____ and division, the answer must have the same number of significant figures as the measured number with the lowest number of significant figures
- 41. all compounds that do not contain carbon and hydrogen
- 43. whether it reacts with acids, bases, and oxygen, gas, or not
- 45. the shape is not definite while the volume is definite and the particles are neither too close nor too far from each other
