Across
- 3. the phase of matter in which particles are moving independent of each other
- 4. pressure of gas particles exerted on a closed container of liquid
- 7. the type of phase change where solid converts directly to gas
- 10. the phase of matter in which particles cannot separate but can glide past one another and flow
- 13. a measure of the force of collisions of gas particles on their container
- 15. a solid with no pattern to its particle arrangement
- 18. the kind of relationship between temperature and pressure; both variables move in the same direction
- 19. O Kelvin; theoretical temperature at which all particle motion stops
- 21. the variable on the x-axis of a phase diagram
- 23. forces acting between molecules to attract them to each other
- 24. the variable on the y-axis of a phase diagram
- 25. the phase change where gas particles convert directly to solid
- 26. the process of converting liquid to gas throughout the liquid; occurs only at certain temperature and pressure
Down
- 1. an absence of gas pressure; it causes water to boil at room temperature
- 2. a temperature scale used among scientists; has no degree symbol
- 5. the phase of matter with the least kinetic energy
- 6. meaning to move out; how gas particles expand
- 8. abbreviation for the unit of pressure called atmosphere
- 9. theory of matter says all particles of matter are in constant motion
- 11. a kind of solid that is made from a repeating pattern
- 12. a measure of the average kinetic energy in a substance; units of Fahrenheit/Celsius/Kelvin
- 14. the conversion of liquid to gas at the surface of a liquid; happens at any temperature between melting point and boiling point
- 16. 760 of this unit equals 1 atm
- 17. the kind of relationship between intermolecular forces and vapor pressure; the variables move in opposite directions
- 20. the temperature scale on which water boils at 100
- 22. the temperature at which a solid transforms to a liquid
