BMCG 2133 THERMODYNAMICS TUTORIAL 03 FACULTY OF MECHANICAL ENGINEERING BMCG 2133 THERMODYNAMICS TUTORIAL 03 1. In what forms can energy cross the boundaries of a system? 2. When is the energy crossing the boundaries of a system as heat and when is it as work? 3. What is an adiabatic process? What is an adiabatic system? 4. What are the sign conventions for heat and work? 5. A gas in a piston-cylinder device is compresses, and as a result its temperature rises. Is this a heat or work interaction for the gas? 6. A room is heated by an iron, which left plugged in. Is this a heat or work interaction? Take the entire room, including the iron, as the system. 7. A room is heated as a result of solar radiation coming in through the windows. Is this a heat or work interaction for the room? 8. An insulated room is heated by burning candles. Is this a heat or work interaction? Take the entire room, including the candles, as a system. 9. What are point and path functions? Give examples. 10. What are mechanisms of heat transfer? 11. A frictionless piston-cylinder device contains 8 kg of superheated water vapor at 500 kPa and 300 o C. Steam is now cooled at constant pressure until 70 percent of it, by mass condenses. Determine the work done and heat transfer during this process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
