Inclass work  Part 1: Assignements  (Submit your work in the Mathematica notebook  as attachment to e-mail))

1) Explain how you do uncertainty calculations for a function 
f (x1,x2,...xn)                           where xi are directly measured observables.

2) Find uncertainty of g =cp/cv  for Ar , using th e  g  formula for ideal gas .  Use the textbook expression from sound velocity method (24) page 114, and data from Example 2 page 57

3) Calculate y for real gas N2 (dinitrogen) use the data from textbook or BIG RED BOOK p644(your handouts) . Note : this is very important!!!! You must check the consistency of units. Use the textbook expression from sound velocity method (35) p 115

4) Find uncertainty for assignment (3)

Inclass work  Part :

1) Plot rotational energies of HCl and those of DCl using Mathematica ( Table and Plot  can help or ListPlot ) Use the needed values from Herzberg (handouts)

2) Plot first 3 vibrational energies of HCl assuming the H.O. model works.Use the needed values from Herzberg (handouts)

3) Plot Morse potential of HCl (textbook can help)  . Use the needed values from Herzberg (handouts)

4) Find the rovibrational parameters B, ve, v0, ve , D and alpha (from model equation 10 page  419  textbook.



Inclass work Part 3;


1) Write down average ROTATIONAL energy (thermodynamics-statisctics)
(you can use partion energy for rotation and use b = 1/k T as variable)

(2) Write down average VIBRATIONAL energy (thermodynamics-statisctics)
(you can use partion energy for rotation and use b = 1/k T as variable)

(3) Write down (you can start with previous expression) ROTATIONAL HEAT CAPACITY contribution 
and plot it as a function of temperature (T,0.001, 100 )  , that should be good for all rotations

(4) Write down (you can start with previous expression)VIBRATIONAL  HEAT CAPACITY contribution and plot it as a function of temperature (T,0.001, 100 ) , (use  T scale 5 * vibrational frequency / k)
