How to measure the property entropy?
Q NO1: A mixture (i.e., thermodynamic system) of 0.182 kg of helium (He) and 0.091 kg ofoxygen (O2) is compressed polytropically (PVn = const.) in a piston-cylinder devicefrom 101.352 kPa and 15.56C to 413.69 kPa according to n = 1.4. Determine for theprocess: (a) the final temperature, (b) the work done, and (c) the heat energy.Clearly mention whether the work is done on or by the mixture, and whether the heatis supplied to or rejected by the mixture to the surroundings.Take the specific heat capacity at constant volume, cv for He = 3.119 kJ/(kg·K) andfor O2 = 0.659 kJ/(kg·K), and the value of gas constant R for He = 2.0769 kJ/(kg·K)and for O2 = 0.2598 kJ/(kg·K).Draw the schematic of piston-cylinder device and display the process on a hypothetical indicator diagram for the process.
