  1. Thermodynamics Chapter 15

  2. Figure 15-1An ideal gas in a cylinder fitted with a movable piston.

  3. - PV=nRT. If n, R, and T are constant, then PV=k- What type of mathematical relationship exists between P & V?- Sketch a plot of P vs. V.

  4. Define these terms:(If you know what each term means, you should be able to compare/contrast!) • Isobaric • Isochoric • Adiabatic • Isothermal • Isovolumetric

  5. Figure 15-22Problem 10

  6. Figure 15-3PV diagram for adiabatic (AC) and isothermal (AB) processes on an ideal gas.

  7. Figure 15-4(a) Isobaric ("same pressure") process. (b) Isovolumetric ("same volume") process.

  8. Figure 15-6PV diagram for different processes where the system changes from A to B.

  9. Figure 15-11Schematic diagram of energy transfers for a heat engine.

  10. Figure 15-15Diagram of an impossible perfect heat engine in which all heat input is used to do work.

  11. Figure 15-16Schematic diagram of energy transfers for a refrigerator or air conditioner.

  12. Figure 15-17Typical refrigerator system

  13. Figure 15-18A heat pump uses an electric motor to "pump" heat from the cold outside to the warm inside of a house.
