Across
- 6. : Solid -> Liquid
- 7. Gas law. When temp is constant, pressure and volume are inversely related
- 9. : particles vibrate in place; closely packed together (shape and volume doesn’t change).
- 13. : 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).
- 15. : Liquid -> Gas
- 17. : transfer energy through electromagnetic (EM) radiation
- 18. : Gas -> Solid
- 19. : Liquid -> Solid
- 22. Gas law, also known as GL’s Law. When volume is constant, pressure and temp are directly related
- 23. : a measure of how much force (push or pull) is on 1 m2 of area (2D space)
- 24. : material that prevents the transfer of energy.
- 25. : transfer energy by colliding particles in direct contact
Down
- 1. zero : atoms/molecules are not moving at all; KE = 0; occurs at 0 K = 273 °C = 460 °F.
- 2. vapor : gas water invisible to the human eye.
- 3. : measure of the average kinetic energy of the particles in a solid, liquid, or gas.
- 4. : reactions where energy is released from the molecules.
- 5. : particles are moving quickly, bouncing off each other (shape and volume can be changed).
- 8. 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.
- 10. : transfer energy through the movement of fluids
- 11. : particles can move past each other; closely packed together (shape changes, volume doesn’t).
- 12. : material that allows the transfer of energy.
- 14. nuclei : solid particles for water vapor to condense onto
- 16. : Gas -> Liquid
- 20. : Solid -> Gas
- 21. : reactions where energy is gained by the molecules.
- 26. Gas law. When pressure is constant, temp and volume are directly related
