A piston cylinder contains 0.01 kg air at 290 K and 96 kPa. A reversible and
adiabatic compression brings it to 1/10 of the initial volume. After this process, combustion
adds 1000 kJ/kg of heat transfer in a constant P process to state 3.
(a) Plot the two processes in a P-v and T-s diagram.
(b) Find pressure and temperature for state 2.
(c) Find temperature for state 3.
(d) Find the work in the two processes (1W2 and 2W3)

Solve one problem only and submit: Problem 5-1 (Energy balance) A Piston Cylinder device contains 5 kg of air (assume ideal gas). Initial temperature is 22℃ Electrical energy is supplied to the system at a rate of 2 kJ/s. The content of the system is stirred by a paddle wheel to ensure uniform temperature everywhere in the system (See Figure). The paddle wheel passes energy to the system at a rate of 0.2 kJ/s. The process is stopped after 10 minutes and the final temperature is 67 °C. The whole process takes place under constant pressure of 200 kPa. 1- Determine the initial and final volume of the system. 2- Determine the heat transferred from the cylinder. 3- Is the process adiabatic? Justify 4- Show the process on a T-v and a P-v diagrams. P AIR ant

A cylinder contains 1 mole of neon gas, which may be treated as ideal. The molar heat capacity of neon is Cv = 1.5R, assumed independent of temperature. Initially, the gas occupies a volume Vi = 5 L and is at a temperature Ti = 300 K. Calculate q, w, Delta U and Delta H for the following processes: Reversible isothermal expansion to Vf= 10 L. Reversible adiabatic expansion to Vf= 10 L. Expansion to Vf= 10 L at a constant external pressure equal to the initial pressure of the gas.
