PROBLEMS TO BE WRITTEN UP AND TURNED IN AT RECITATION

     This problem is due at the beginning of lecture on Wed 04/27.  The 
     problem should be written on a single sheet of paper (front and back);
     please then join this assignment together with the turn-in problem
     from HW33 using a single staple.  For full credit, the work must be 
     neat, with clearly labeled diagrams (if useful).  The labels must be 
     in BOTH words and symbols.  For each part of the problem, you must 
     BRIEFLY explain your strategy in words, as well as neatly showing 
     your physics equations and math, with proper units. 

               Wolfson Chapter 22 problem 45, p. 565. (10 points)

     The description of the action in this problem is not exceptionally
     clear; it intends to describe a free expansion from a tiny volume
     of 1 cubic centimeter into a large volume of 1 cubic meter.  The
     "initial gas pressure" is the pressure of the gas when it is
     confined in the 1 cubic-centimeter volume.  GBA
