TAILIEUCHUNG - Lecture Thermodynamics: An engineering approach (8/e): Chapter 3 - Yunus A. Çengel, Michael A. Boles

Chapter 3 - Properties of pure substances. We start this chapter with the introduction of the concept of a pure substance and a discussion of the physics of phase-change processes. We then illustrate the various property diagrams and P-v-T surfaces of pure substances. After demonstrating the use of the property tables, the hypothetical substance ideal gas and the ideal-gas equation of state are discussed. | Chapter 3 Properties of Pure Substances Study Guide in PowerPoint to accompany Thermodynamics: An Engineering Approach, 8th edition by Yunus A. Çengel and Michael A. Boles We now turn our attention to the concept of pure substances and the presentation of their data. Simple System A simple system is one in which the effects of motion, viscosity, fluid shear, capillarity, anisotropic stress, and external force fields are absent. Homogeneous Substance A substance that has uniform thermodynamic properties throughout is said to be homogeneous. Pure Substance A pure substance has a homogeneous and invariable chemical composition and may exist in more than one phase. Examples: 1. Water (solid, liquid, and vapor phases) 2. Mixture of liquid water and water vapor 3. Carbon dioxide, CO2 4. Nitrogen, N2 5. Mixtures of gases, such as air, as long as there is no change of phase. State Postulate Again, the state postulate for a simple, pure substance states that the .
