[Under Construction]

 

 

Review Chapter 14

1.    What are the condensed states of matter?  Why are they considered this? (think compressibility)

2.    Compare the properties of the three phases of matter.

solid                                                        liquid                                                    gas

 

 

3.    Intermolecular forces account for the increasing order of the molecules in a substance.  Rank the phases in increasing order.

4.    How does the kinetic molecular theory account for the phase of a substance at room temperature. (think kinetic and bond energy)

5.    Which variable in the ideal gas law directly relates to the kinetic energy of gas?

6.    How are the intermolecular forces in a solution and the boiling point of a solution related?

7.    Compare the strength of the intra and intermolecular forces in a solution.

8.    Rank the intermolecular forces with regard to strength from strongest to weakest.

9.    What kind of intermolecular forces are dispersion forces?

10.    How does the size of a gas molecule relate to the size of its dispersion force?

11.    Dipole-dipole forces are found in what type of molecules?

12.    What elements are normally involved in hydrogen bonding?

13.     How are the intermolecular forces in a solution and the viscosity and surface tension of a solution related?

14.    What are some of waters unique properties?

 

15.    What is the name given to the smallest repeating unit of a crystalline solid?

16.    What are the types of crystalline solids.

17.    Why are amorphous solids often called imperfect solids?

18.    What does the vapor equilibrium of a solution account for the different kinetic energies of molecules in a solution?

19.    Be able to interpret the diagram on pages 462 (14-7) and 480 (14-31) and relate them to the sizes and weights of gases, size of the gases, their vapor pressure, and their intermolecular forces.

 

 

 

20.    Be able to interpret the diagram on pages 488 (14-39) and relate them to the sizes and weights of gases, size of the gases, their vapor pressure, and their intermolecular forces.

 

 

 

 

21.    What does the triple point of a solution represent?

22.    What are the phase changes?

 

23.    What is the difference between heat of fusion and heat of vaporization?
