II.  Describe the four basic principles behind the kinetic theory of gases.



III.  Calculate the following

   1.  Calculate the number of grams of boiling water which will evaporate upon the 
        addition of 1.5 x 107 joules of heat.  ( The heat of vaporization for water is 
        2.26 x 103 j/g )


   2.  Calculate the amount of heat necessary to melt 150 g of ice at a constant temperature 
        of 0oC .  ( The heat of fusion for water is 335 j/g.






IV.  Short essays

1.  If one is trapped on thin ice, explain why it is best to lie down rather than continue 
     standing.


2.  Describe how air pressure and weather systems are related.


3.  Explain what is occurring when one's blood pressure is taken and also 
     state the optimum values for a young adult.


4.  Describe how pressure affects the boiling point of a liquid.


5.  Make a drawing of a distillation apparatus and explain it's operation.


6.  State four examples of the process of deliquescence.


7.  Describe how it is possible for the snow level on a mountain range to decrease
     other than by melting.


8. Explain why an empty glass coffeepot on a hot stove will explode while one filled   
      with water will not. 


9.  Explain the meaning of a liquid crystal and state at least two of its uses.
