e 115 Engineering Thermodynamics Fall 2009 University of California Problem set 2 Due: Friday, September 4 th , in lecture 1) (35 points) One mole of a monatomic ideal gas, initially at 300K and a pressure of 2 atmospheres is subjected to a series of reversible processes ( P ext = P gas + d P ) that ultimately return the system to its original state. a) The first series of processes entails: 1) an isobaric tripling of the volume, 2) an isochoric tripling of the pressure, and 3) a return to the original state along a path prescribed by an equation of the form P = aV 2 + b where pressure is in atmospheres and volume in liters. Make a sketch of the process. Determine the coefficients a and b , and then, the heat and work interactions and the internal energy and enthalpy change of the system associated with each step. b) In a variation of process 1 described in part a), the pressure varies as the volume is tripled. Letting V 1 represent the initial volume, and P 1 represent the original pressure of the gas, the

    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.
