Unformatted text preview: data. Assumptions The process is quasi-equilibrium. Analysis Plotting the given data on a P-diagram on a graph paper and evaluating the area under the process curve, the work done is determined to be 0.25 kJ . 3-2C A liquid that is about to vaporize is saturated liquid; otherwise it is compressed liquid. 3-10C At supercritical pressures, there is no distinct phase change process. The liquid uniformly and gradually expands into a vapor. At subcritical pressures, there is always a distinct surface between the phases. 3-14C Yes. Otherwise we can create energy by alternately vaporizing and condensing a substance. P 1 2 T =...
