  1. 3. PRESSURE The pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system.
  2. 6. From the Latin word "cohaerere" meaning "stick or stay together." The action or property of like molecules sticking together, being mutually attractive.
  3. 8. CELL The most basic and least volume consuming repeating structure of any solid. When it repeats itself, the network is called lattice.
  4. 10. The process of chilling a liquid below its freezing point,without it becoming solid.
  5. 11. TEMPERATURE The temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
  6. 12. Another type of bulk property defined as a liquid's resistance to flow.
  7. 13. POINT The temperature at which its vapor pressure is equal to the pressure of the gas above it.
  8. 16. FORCES Any force that holds together the atoms making up a molecule or compound.The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity.
  9. 17. The ability to form instantaneous dipoles. Determine the dynamical response of a bond system to external fields,and provide insight into a molecule's internal structure.

  1. 1. BOND The electrostatic attraction between two polar groups that occurs when a hydrogen atom covalently bond to a highly electronegative atom such as nitrogen, oxygen or fluorine.
  2. 2. TENSION This is caused by the attraction of the particles in the surface layer by the bulk of the fluid, which tends to minimize surface area.
  3. 4. FORCE The weakest intermolecular force. Sometimes called an induced dipole-induced dipole attraction.
  4. 5. EQUILIBRIUM This exists once a reversible reaction ceases to change its ratio of reactants or products, but substances move between the chemicals at an equal rate.
  5. 7. FORCES Forces which mediate interaction between molecules.
  6. 9. POINT The temperature and pressure at which solid, liquid, and vapor phases of a particular substance coexist in equilibrium.
  7. 12. DER WAALS FORCES Named after the Dutch scientist. Residual attractive or repulsive forces between molecules or atomic groups that do not arise from covalent bonds, nor ionic bonds.
  8. 14. CURVE Shows how the temperature changes as a substance is heated up at a constant rate.
  9. 15. A molecule in which a concentration of positive electric charge is separated from a concentration of negative charge.
  10. 18. The tendency of dissimilar particles or surfaces to cling to one another.
