States of Matter

5. Mr defined in notes as the sum of relative atomic masses.
6. A liquid’s ability to move freely because particles can move past each other.
9. What gases can do easily because there is lots of space between particles.
10. Forces that must be overcome when a liquid becomes a gas (named explicitly).
12. Same temperature value as melting point for a pure substance, but opposite direction.Specific temperature where bubbles form throughout a liquid to become gas.
13. What atoms do in a solid while staying in position.
16. Crystal used in the liquid diffusion demo (chemical name in notes).
19. Property of solids and liquids: same amount of space is kept.
20. “Mirror image” graph of a heating curve.
24. Describes the particle arrangement in solids (fixed and orderly).
26. Particle impacts with container walls that create gas pressure.
27. Flat parts of heating/cooling curves where state changes but temperature doesn’t.
28. Change of state that happens at the surface over a range of temperatures.
29. Theory used to explain particle arrangement, movement, and state changes.

1. Factor that speeds up evaporation mentioned alongside warmth of the liquid.
2. Gas to liquid on cooling as particles lose energy and group together.
3. End-point of diffusion: concentration becomes the same everywhere.
4. Movement of particles in all directions with no set path.
7. Force per unit area inside a gas container caused by particle impacts.
8. Property only solids keep (without a container).
9. Relationship: gas volume increases as temperature increases (one word).
11. Graph showing temperature changes as heating continues through state changes.
14. Typical property of solids mentioned in the notes (mass per unit volume is high).
15. White “smoke” solid formed when ammonia gas reacts with hydrogen chloride gas.
17. Relationship: when pressure increases, gas volume decreases (one word).
18. Diffusion occurs from a region of higher ___ to lower ___.
21. The smelly liquid in the “spilt in the corner of a room” diffusion example.
22. Specific temperature where a solid becomes a liquid.
23. How liquid particles move to allow liquids to take container shape.
25. Specific temperature where bubbles form throughout a liquid to become gas.
