A piston-cylinder assembly fitted with a slowly rotating paddle wheel contains 0.19 kg of air, initially at 300 K. The air undergoes a constant-pressure process to a final temperature of 440 K. During the process, energy is gradually transferred to the air by heat transfer in the amount 12 kJ. Assuming the ideal gas model with k = 1.4 and negligible changes in kinetic and potential energy for the air, determine the work done by the paddle wheel on the...

Problem 1 A piston-cylinder system contains a paddle stirrer (a paddle with blades that can stir the contents of the cylinder). The cylinder contains a gas that is initially at 150 kPa and occupies a volume of 0.196 m3 . The piston is unrestrained and has a cross-sectional area of 0.196 m2 . 20 kJ of electrical energy is supplied to the paddle stirrer, resulting in the piston moving up by 0.2 m. During this process, 5.27 kJ of heat...

(i) Define pure substance and comprehensively describe the phase changes of a pure substance considering water as an example. Use diagrams to illustrate your understanding of this point.. (1 mark) (ii) The variations of properties during phase-change processes are best studied and understood with the help of property diagrams including the T-v, P-v, and P-T diagrams for pure substances. Taking water as an example, comprehensively sketch and discuss how these tables (1 mark)...

pts per question) 1. A 2 m piston cylinder device contains nitroen gas at 200 kPa and 350K. Now heat is transferred to the nitrogen in the tank and the pressure of nitrogen rises to 900 kPa and volume is maintained at same. The boundary work done during this process is (a) 1080 kJ (b) 840 k (c)240 k 2. A heat engine receives heat from a source at 727°C and rejiects the waste heat to a sink at 27°C,...
