- 32. method for separating mixtures that separates solids of different sizes.
- 35. method for separating mixtures that removes a liquid from a solution to leave a solid material.
- 36. chemical property of matter on whether the substance can be easily decomposed or not.
- 38. the substance which remains in the strainer.
- 39. method of separating mixtures composed of liquid and solid ingredients.
- 41. substance formed when two or more chemical elements are chemically bonded together.
- 43. state of matter that has a definite shape and volume.
- 44. ___Change - occurs when the internal make-up of the matter stays the same, even after the change, only shape, size and state are altered.
- 46. method of separating mixtures commonly used in farms.
- 47. the liquid that passes through the strainer.
- 48. ___Activity - chemical property of matter on whether the material is more active or less active than other members of its chemical family.
