ME 311 Reading Guide #3 1/3 ME/NE 311 Introduction to Thermal and Fluid Sciences Reading Guide #3 Chapter 2 Sections 8 through 10, 4, and 11 (Read in this order) Section 2.8: Work 1. The first law of thermodynamics is a relationship among ___________________, heat, and _______________________________________________. 2. The three types of work to be considered in this class are _______________________________ work, __________________________ work, and “expansion or compression” work, which I prefer to call “boundary” work. 3. A state of _____________________ implies that all properties are uniform throughout the system. 4. Define a quasi‐equilibrium process. ____________________________________________________________ ______________________________________________________________________________________________________ 5. Does the amount of work, defined as the area under the curve in Figures 2‐17 and 2‐18, depend upon the path taken between the first and second states (i.e., point 1 and point 2)? Y or N 6. Which of the following two equations is correct and why? dW = PdV or δ W = PdV ______________________________________________________________________ ___________________________________________________________________________________________________ 7. An inexact differential, δ , is used to represent a path dependent process such as work, whereas the exact differential, d, is used to represent the change in a path independent ______________________________ such as energy.
