- 7. Separating a homogeneous mixture composed of 2 substances with different boiling points
- 8. Tells how hot or cold an object is
- 9. Determined when a certain quantitative value is relatively close to the “true” value
- 12. The branch of chemistry that applies physics to the study of chemistry
- 15. A process of determining the extent of the dimensions, quantity, or extent of something
- 17. A process of separating solid matter and fluid from a mixture with a filter medium in which only the fluid can pass
- 19. Occurs when the internal make-up of the matter stays the same
- 22. Has definite shape and volume
- 24. The ability/characteristic of a substance to react with other substances such as air, water, acid & base
- 25. A substance formed when two or more elements are chemically joined
- 26. Also known as intrinsic physical property
- 27. Type of heterogeneous mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance.
- 28. The consistency of a result
- 31. Branch of chemistry that studies about carbon and its compounds; the study of the chemistry of life
- 35. Type of mixture whose composition varies from one position to another
- 36. Solid particles are allowed to settle first, then the liquid is poured into another container leaving behind the solid particles
- 37. Also known as extrinsic physical property
- 38. The phase transition in which a substance changes from solid to gas without ever through the liquid state
- 40. The phase transition in which liquid turns to gas
- 41. The study of the chemistry of matter and the development of tools to measure properties of matter
- 42. Branch of chemistry that studies about inorganic compounds, or compounds that don't contain a C-H bond
- 43. A chemical property whether the substance can be easily decomposed or not
- 45. Chemical property whether it reacts with acids, bases, gases or not
- 46. The smallest part of an element
- 47. It is the ratio of the mass of an object to the volume it occupies
- 48. is a system in which an ordinary decimal number is expressed as the product of a number between 1 and 10 times 10 raised to a power; expressed as N x 10n
Down
- 1. The simplest form of matter
- 2. Any substance that has mass and takes up space by having volume
- 3. An effect only exclusive to colloids: the ability to scatter a beam of light that passes through it.
- 4. A sample of matter with definite & constant composition & distinct chemical properties.
- 5. The study of chemical processes that occur inside of living organisms
- 6. A process in which a conversion factor written in a form of ratio is used to change the units given in the data to the units desired
- 10. The sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.
- 11. Process of separating elemental metals from other particles in a mixture with the use of a magnet
- 13. Composed of two or more substances combined physically in variable proportions
- 14. The quantity of matter in the object; determined by weighing the obect
- 16. Occurs when a substance is converted to a new substance
- 18. The amount of space occupied by a substance
- 20. Also called solution; Type of mixture in which the components are uniformly distributed throughout
- 21. The digits in any measurement that are known with certainty with an additional one digit which is uncertain
- 23. The phase transition in which solid turns to liquid; can be used in extricating mixtures that contain 2 substances with different melting points
- 29. The phase transition in which gas turns to liquid
- 30. Chemical property whether the substance undergoes combustion or not
- 32. The phase transition in which liquid turns to solid
- 33. Another method of separating complex mixtures; The mixture is dissolved in a fluid which carries it through a structure holding another material. The various constituents of the mixture travel at different speeds, causing them to separate.
- 34. Has indefinite shape but definite volume
- 36. The phase transition in which gas transforms into solid without passing through the liquid phase
- 39. Has indefinite shape and volume
- 43. A type of heterogeneous mixture that consists of coarse particles visible to the naked eye
- 44. Chemical property whether the substance can damage an organism or not
