Unformatted text preview: e 115 Engineering Thermodynamics Fall 2009 University of California Problem set 1 Due: Wednesday, September 2 nd , in lecture In the prior and forthcoming lectures the topic of interest will be processes of varying type that can involve an ideal gas. Examples include processes in which either the temperature T , or the pressure P , or the volume V of a fixed number of moles of ideal gas is held fixed. In thermodynamics we will often need to determine the change in the value of a thermodynamic quantity as the result of a process that takes the system from some initial state or condition, for example specified by some P 1 , V 1 , T 1 to some new state specified by P 2 , V 2 , T 2 . It will be important to distinguish those thermodynamic quantities for which the change is independent of the path taken, so-called state functions or point functions, from those in which the details of the path matter, the so-called path functions. For state functions or point functions, the differential expressions are exact differentials. Please refer to the Chapter 1 handout as needed, or a calculusdifferential expressions are exact differentials....
