  1. What is molar heat capacity? 

    2.  

     

  2. What is specific heat capacity?

    3.  

     

  3. The kinetic energy of a system is directly related to its temperature.  So if we heat a
    system we                     its kinetic energy.

    4.  

     

  4. What are two conditions under which a gas can be heated?

      5.  



     

     

  5. What are the values for:

      6.  

    • Cp
    • Cv

     

     

  6. Why is Cv<Cp?

    7.  

     

  7. When energy is added to a molecule there are three potential forms of motion that it can be transferred into:

      8.  




     

     

  8.                                is the only motion that directly affects temperature.

    9.  

     

  9. The values 3/2 R and 5/2 R are only applicable to                    ideal gases. Why?

    10.  

     

  10. This means that the calculated molar heat capacities are often          than actual molar heat capacities.

    11.  

     

  11.  What equation relates ΔE to heat capacity?

      12.  

    • Under what conditions can you use this equation?

      •  

    • Under what conditions does ΔE = q?

     

     

  12. What equation relates ΔH to heat capacity?

      13.  

    • Under what conditions can you use this equation?

      •  

    • Under what conditions does ΔH=q?

     

     

  13. Which value of R do we use in these equations?

    14.  

     

  14. Fill in the chart….

                 

     

     

  1. Consider a sample containing 5 moles of a monatomic ideal gas that is taken from State Aà State B by 2 different paths.  For each step, assume that the external P is constant and equals the final P of the gas for that step.  Calculate the values of q, w, ΔH and ΔE for each step along the 2 paths and the totals for the 2 paths.  What do the totals demonstrate?
