Across
- 5. the process by which molecules undergo the a spontaneous transition from the liquid phase to the gas phase.
- 7. The temperature at which a solid and liquid phase may coexist in equilibrium.
- 11. The pressure required to liquefy a gas (vapor) at its critical temperature.
- 13. a phenomenon in which the surface of a liquid, where the liquid is in contact with gas, acts like a thin elastic sheet.
- 14. the enthalpy change experienced on a mole by mole basis of some substance undergoing a phase change from liquid to vapor/gas.
- 17. the temperature at which a liquid changes to a solid.
- 19. the settling of particles or sediment onto a surface.
- 20. the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
- 21. the temperature and pressure at which solid, liquid, and vapor phases of a particular substance coexist in equilibrium.
- 22. Also called migration. an intermingling of molecules, ions, etc., resulting from random thermal agitation, as in the dispersion of a vapor in air.
Down
- 1. a chart showing the thermodynamic conditions of a substance at different pressures and temperatures.
- 2. the point at which two phases of a substance initially become indistinguishable from one another.
- 3. Liquid that evaporates at room temperature, or vaporizes easily.
- 4. rapid change of water into steam.
- 6. The interaction between contacting surfaces of a liquid and a solid that distorts the liquid surface from a planar shape and causes the liquid to rise or fall in a narrow tube.
- 8. the transition from the solid phase to the gas phase without passing through an intermediate liquid phase.
- 9. The temperature above which a gas cannot be liquefied; the temperature above which a substance cannot exhibit distinct gas and liquid phases.
- 10. the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.
- 12. a gas that does not behave as an ideal gas due to interactions between gas molecules.
- 15. temperature at which a liquid boils and turns into vapor.
- 16. the flow of a gas through a small orifice at such density that the mean distance between the molecules is large compared with the diameter of the orifice.
- 18. the condition existing when a chemical reaction and its reverse reaction proceed at equal rates
