Matter 2 (Changes)

3. The amount of matter(mass) in a given space(volume).
4. A state of matter in which the atoms are broken down into a cloud of protons, neutrons, and electrons.
5. An exothermic chemical reaction in which a substance combines with Oxygen to produce thermal energy, along with light and carbon dioxide.
8. Any change in the size, shape, form, or state of matter in which the matter's identity remains the same.
9. The relative extent of something; a thing's overall dimensions or magnitude; how big something is.
13. A homogeneous mixture who's elements and/or compounds are evenly mixed at the molecular level but are not bonded together.
15. Process that produces chemical change, resulting in new substances that have properties different from those of the original substances.
18. The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
20. The physical property possessed by an object of producing different sensations on the eye as a result of the way the object reflects or emits light.
21. The temperature at which a liquid boils.
24. The temperature at which a solid melts.
27. Change of matter from a liquid state to a solid state.
28. The measure of how much solute can be dissolved in a certain amount of solvent.
29. Amount of matter in an object

1. Change of matter from a liquid state to a gaseous state.
2. Changing from a gas to a liquid.
6. Any characteristic of matter-such as color, shape and taste-that can be detected by the senses without changing the identity of the matter.
7. A state of matter with a definite volume but an indefinite shape. The molecules move fast and slide against each other.
10. The ability to for a substance or material to light or catch on fire and burn.
11. Characteristic of something that permits its change to something new.
12. Substances that exist before a chemical reaction begins.
14. Physical properties that do not change when the size of the object changes.
15. Any change of a material into a new material with different properties.
16. When a solid changes directly to a gas.
17. Describes how easily something reacts with something else.
19. Physical properties that change when the size of the object changes.
22. A state of matter with no definite shape and volume. The molecules are spread apart and move at high speeds.
23. Change of matter from a solid state to a liquid state.
25. A solid that comes back out of its solution because of a chemical reaction or physical change.
26. A state of matter that has a definite shape and volume. The molecules are tightly packed and vibrate.
