    Please write answers on your answer-paper.

1. To select the best answer (10pts)

    (1). (2 pts) A bomb calorimeter (i.e.like the one I brought to class) measures ( )

    a. the work done by the system at constant volume. b. the work done by the system at constant pressure. c. the heat released by the system at constant volume. d. the heat released by the system at constant pressure.

(2). (2 pts) Which of the following is not one of the Laws of Thermodynamics. ( )

    a. The entropy at 0C is zero.

    b. For an isolated system a spontaneous process results in an increase of the entropy

    of the system.

c. The entropy of the universe increases.

    d. ;E = q +w

(3). (2 pts) If the first Law of Thermodynamics is stated as ;E = q - w, which of the

    following statements is true? ( )

    a. For w > 0, this represents work done by the system.

    b. For q >0, this represents heat released by the system. c. For w > 0, this represents work done on the system.

    d. None of the above.

(4). (2 pts) Which of the following is false with regards to a state function? ( )

    a. Changes in state functions only depend on the initial and final states. b. Enthalpy is a state function.

    c. Heat at constant pressure may be considered a state function d. Entropy is a state function

    e. Work is a state function.

    (5) (2 pts) There is a spontaneous process carrying out in a closed system: ( )

    -1-1a. ;S> 0 J.mol.K sys.

    -1-1b. ;S< 0 J.mol.K sys.

    -1-1c. ;S= 0 J.mol.K sys.

    d. None of the above.

    2 .Match the best description from the right column with the formula from the left column (there is only one best match) (10 pts)

    3. (15pts)Thermodynamics: As it was known thermodynamic data for all compounds at 298.15 K, 1 bar
