PHY 113 -- Extra Practice Problem PHY 113 - Extra Practice Problem for Chapters 19-22

This problem summaries many of the topics covered in these Chapters. Consider the process described by the P-V diagram above, assuming that the medium of the process is 1 mole of an ideal gas having a specific heat ratio g º CP/CV = 1.4. The numerical values are V1 = 1m3, V2 = 2m3, P1 = 101300Pa, and P2 = 202600 Pa.

  1. Complete the following table of the internal energy, heat added to system, and work done by the system:

    DEint DQ DW
    A ® B
    B ® C
    C ® D
    D ® A

  2. Which step of the process has the highest temperature, and which has the lowest temperature?

  3. Determine the efficiency of this process.
