Reminder
Intermolecular Forces are not break covalent bonds
Boiling, melting break INTERMOLECULAR FORCES not covalent bonds
3) IMF  attraction  B.P  M.P  Viscosity  V.P
4) LDF increases with increased surface area and increased size due to POLARIZABILITY

1. Liquid water is placed in a jar, which is then sealed. Unless water vapor is also added before the jar is sealed, a dynamic equilibrium between the liquid and vapor phases cannot be attained.
2. At an atmospheric pressure of 700 mm Hg, water boils at 97.7°C. This temperature is termed the boiling point of water at 700 mm Hg of pressure.
3. The normal boiling point of water is the temperature at which the vapor pressure of liquid water equals the atmospheric pressure.

4. At 20°C alcohol tends to “wet” or spread out on a piece of wax paper more readily than water. From this observation we can say that at 20°C alcohol has a lower surface tension than water.
5. In general, the larger the intermolecular forces existing between molecules, the lower the temperature at which a liquid is converted to a solid at 1 atm of pressure.
6. CO (s) will sublime completely to form CO (g) at any temperature below its triple point providing the pressure above the solid phase is always below the equilibrium vapor pressure.

25. A heating curve shows the change in temperature of a substance as a function of the time it is heated. It is like a phase diagram, but instead of pressure as one of the axes, time is plotted. Figure 11.3 shows an idealized heating curve for a substance at a constant pressure of 1 atm beginning with a solid at a low temperature. Explain what physical changes in the substance are occurring in the regions from points A to B, B to C, C to D, D to E, and E to F. What phases are present at temperatures x and y?
