For isentropic process involving ideal gases, starting with k P1 P2 = k-1 T2 T1 Derive the formula

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?

For a thermodynamic process, when delta Hsys > 0, and delta Ssys < 0, the process is (spontaneous at all temperatures, non-spontaneous at all temperatures or spontaneous only at high temperatures).

Carbon dioxide (molar mass 44 kg/mol) expands reversibly in a perfectly thermally insulated cylinder from 3.7 bar, 220 degrees Celsius to a volume of 0,085 m³. If the initial volume occupied was 0,02 m³, calculate the gas constant, adiabatic index,final pressure and work input. Assume nitrogen to be a perfect gas and take cv=0,63 KJ/kgK

Q3: In a steam jacket cylinder, steam expands from 5 bar to 0.12 MPa according to a law pv1.05 = constant. Assuming that initial dryness fraction is 90%, calculate the work done and heat supplied for 0.5 kg of steam during the expansion.

CO2 needs to be compressed from p1=1bar, t1=300k to p2=40bar to transport it to remote sites for sequestration. what is the minimum energy requirement per kg of CO2 for the compressor? Should the compressor operate adiabatically or isothermally for the best energy efficiency? The environment is at Tenv=300k. Use accurate thermodynamic data for CO2 in this problem.

A gas initially at 125 kPa, 7 o C is compressed to 932 kPa. Determine the final temperature in o C for (a) adiabatic with k = 1.4 (b) polytropic with n = 1.3

A well-insulated 4 × 4 × 5 m³ room, initially at 10 °C, is heated by the radiator of a steam heating system. The radiator has a fixed volume of 150 L and is initially filled with superheated water vapor at 200 kPa and 200 °C. After 30 minutes, the pressure of the steam is observed to drop to 100 kPa as a result of heat transfer to the room. Assume constant specific heats for air. (a) (b) (d) Sketch a thermodynamic diagram for the process of the steam. Determine the final temperature of the steam. Based on the final state you found, make any corrections needed to your diagram in (a). neglected. the air. Write the First Law for the air and steam, and indicate which terms can be Assuming the air has a uniform temperature, find the final temperature of
