Document Summary
Multiple choice, matching, open ended problems, ordering questions, and short answers. 4 other problems combine midterm 1 and 2 material. Coulomb law and resulting attraction/repulsion between charged particles and between charged segments of molecules. Molecular polarizability and induced dipole moment; dipole-dipole forces. Weaker than the forces associated with covalent bonds. Several types can be present at the same time. Strong intermolecular forces imply: higher melting point and higher deltah fusion, higher boiling points and higher deltah vaporization, higher surface tension, higher viscosity, lower vapor pressure. Specific heat capacity (cs) the amount of heat required to raise the temperature of one gram of the substance by one degree. Q = mass * cs * deltat. Phase diagram graphically represents the boundaries between conditions at which a substance exists as a solid, liquid, or gas. Water is abnormal because it has a negative fusion slope unlike other liquids which have a positive fusion slope. Unit cell is the basic repeating structural unit.
