States of Matter

1. the physical change of liquid to solid by removal of energy as heat, also known as solidification.
3. the amount of energy as heat that is needed to vaporize one mole of liquid at the liquid’s boiling point at constant pressure.
8. one in which there is no net loss of total kinetic energy.
9. the temperature above which the substance cannot exist in the liquid state.
11. a force that tends to pull adjacent parts of a liquid’s surface together, thereby decreasing surface area to the smallest possible size.
14. the total three-dimensional arrangement of particles of a crystal.
17. liquids that evaporate readily, have relatively weak forces of attraction between their particles.
18. the physical change of a solid to a liquid by the addition of energy as heat
20. the pressure exerted by a vapor in equilibrium with its corresponding liquid at a given temperature.
21. indicates the temperature and pressure conditions which the solid, liquid, and vapor of the substance can coexist at equilibrium.
23. the process by which a gas changes to a liquid.
24. any part of a system that has uniform composition and properties.
25. process by which gas particles pass through a tiny opening.
26. a substance in which the particles are arranged in an orderly repeating pattern
27. process by which a liquid or solid changes to a gas

1. substance that can flow and take the shape of its container.
2. substances that retain certain liquid properties even at temperatures at which they appear to be solid.
4. a graph of pressure versus temperature that shows the conditions under which the phases of a substance exist.
5. the change of state from a solid directly to a gas.
6. gas that does not behave completely according to the assumptions of the kinetic-molecular theory
7. based on the idea that particles of matter are always in motion.
10. the lowest pressure at which the substance can exist as a liquid at the critical temperature.
12. one in which the particles are arranged randomly
13. the attraction of the surface of a liquid to the surface of a solid, is a property closely related to surface tension.
14. indicates the critical temperature and critical pressure.
15. spontaneous mixing of the particles of two substances caused by their random motion
16. the change of state from a gas directly to a solid.
19. temperature at which a solid becomes a liquid
20. the process by which particles escape from the surface of a non boiling liquid and enter the gas state.
22. is the conversion of a liquid to a vapor within the liquid as well as at its surface.
