Phases

7. , Gas  Solid
9. , material that prevents the transfer of energy.
10. zero , atoms/molecules are not moving at all; KE = 0; occurs at 0 K = 273 °C = 460 °F.
12. , Solid  Liquid
13. , Liquid  Solid
15. , material that allows the transfer of energy.
18. Law , When temp is constant, pressure and volume are inversely related
19. , transfer energy by colliding particles in direct contact
22. , a measure of how much force (push or pull) is on 1 m2 of area (2D space)
23. Molecular Theory , 1. All particles of matter have KE (except absolute zero). 2. Particles of matter (atoms or molecules) are in constant, random, rapid motion. 3. Gases are made of large numbers of tiny spherical particles very far apart from one another. 4. Gas is mostly empty space.
25. , Liquid  Gas
26. Law , When pressure is constant, temp and volume are directly related

1. , transfer energy through the movement of fluids
2. , transfer energy through electromagnetic (EM) radiation
3. nuclei , solid particles for water vapor to condense onto
4. , Solid  Gas
5. reactions , reactions where energy is released from the molecules.
6. , particles can move past each other; closely packed together (shape changes, volume doesn’t).
8. , particles are moving quickly, bouncing off each other (shape and volume can be changed).
11. , transfer of thermal energy from one object to another. Energy is always transferred from hot (where there is more energy) to cold (where there is less energy).
14. reactions , reactions where energy is gained by the molecules.
16. , Gas  Liquid
17. , particles vibrate in place; closely packed together (shape and volume doesn’t change).
20. , measure of the average kinetic energy of the particles in a solid, liquid, or gas.
21. Law (GL’s Law) , When volume is constant, pressure and temp are directly related
24. vapor , gas water invisible to the human eye.
