Properties of Matter

1. A process where one or more substances are converted into entirely new substances.
3. The ratio of mass to volume; how tightly packed the particles are in a substance.
6. A form of energy that travels in waves and is not considered matter.
7. The chemical symbol for the element Tin.
9. Substances formed when two or more different elements are chemically bonded together.
11. A characteristic like boiling point or color that can be observed without changing the substance.
12. The flat part of a phase change graph where temperature remains constant while the state changes.
13. The state of matter where particles are tightly packed and vibrate in fixed positions.
15. A change in a substance's appearance or state that does not change its chemical identity.
21. A reaction that feels cold to the touch because it absorbs energy from its surroundings.
23. A logical interpretation or conclusion based on prior knowledge and observations.
25. A measure of the average kinetic energy of the particles in a sample
28. Data that describes properties or characteristics using the five senses rather than numbers.
29. of Best Fit A straight line drawn through the center of data points on a scatter plot to show a trend.
30. The chemical symbol for the element Iron.
31. A characteristic that describes a substance's ability to change into a different substance.
33. A mixture where the different components are easily seen and not uniformly spread.

2. The law that states atoms are only rearranged, not created or destroyed, in a reaction.
4. A reaction that feels hot because it releases energy into its surroundings.
5. The act of using your senses to gather information about a phenomenon or experiment.
8. The chemical symbol for the element Manganese.
10. The small number below an element symbol that shows how many atoms of that element are present.
14. The state of matter with a definite volume but no definite shape.
16. A mixture that is uniform in composition; it looks the same throughout.
17. The large number placed in front of a chemical formula to balance an equation.
18. The state of matter with no definite shape or volume; particles move rapidly and are far apart.
19. Data that is expressed using specific numbers, measurements, or counts.
20. Anything that has mass and takes up physical space.
22. A pure substance made of only one kind of atom that cannot be broken down further.
24. Substance A sample of matter, either a single element or a single compound, that has definite properties.
26. Two or more substances that are physically combined but can be separated by physical means.
27. of the amount of matter contained within an object.
32. The chemical symbol for the element Magnesium.
