On a p–V diagram, sketch a cyclic process that consists of an isothermal expansion followed by an isobaric compression, and lastly followed by an isometric process.
Answer to relevant QuestionsIn Fig. 12.19, the plunger of a syringe is pushed in quickly, and the small pieces of paper in the syringe catch fire. Explain this phenomenon using the first law of thermodynamics. (Similarly, in a diesel engine, there are ...Suppose that after the final process in Fig. 12.22 (Exercise 10), the pressure of the gas is decreased isometrically from 1.0 x 105 Pa to 0.70 x 105Pa, and then the gas is compressed isobarically from 1.0 m3 to 0.80 m3. What ...One mole of an ideal gas is taken through the cyclic process shown in Fig. 12.24. (a) Compute the work involved for each of the four processes. (b) Find ∆U, W, and Q for the complete cycle. (c) What is T3? A quantity of an ideal gas undergoes an isothermal expansion at 20 oC and does 3.0 x 103 J of work on its surroundings in the process. (a) Will the entropy of the gas (1) increase, (2) remain the same, or (3) decrease? ...A gasoline engine has a thermal efficiency of 28%. If the engine absorbs 2000 J of heat per cycle, (a) What is the net work output per cycle? (b) How much heat is exhausted per cycle?
