4. Notation – method of writing really large or really small numbers in a more concise form
10. – chemical laboratory process used to separate mixtures
14. - a substance's ability to deform under pressure
15. – the process where a mixture is separated through spinning

20. – a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance
22. – the measure of the ease at which an electric charge or heat can pass through a material
23. – the process by which a substance changes from the solid phase to the liquid phase
24. – the study of macroscopic, and particulate phenomena in chemical systems
25. – deals with synthesis and behavior of inorganic and organometallic compounds
29. – the unit of measurement for amount of substance in the International System of Units
30. – a property referring to the ability for a given substance, the solute, to dissolve in a solvent
33. – the form of an object or its external boundary, outline, or external surface
34. – the state of being stable
36. – refers to how close two or more measurements are to each other
38. – the degree to which a chemical substance or a particular mixture of substances can damage an organism
39. – the basic unit of length in the SI system of units
40. – refers to the phase transition in which matter changes state from a solid immediately into a gas
43. – a measure of distance
44. – a measure of mass per volume
45. – special type of homogeneous mixture composed of two or more substances
46. substance – a material that has a constant composition
48. – a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds
49. – the technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid

Down

1. – he base unit of time in the International System of Units
2. – a coherent, typically large body of matter with no definite shape
