A fixed thermally conducting cylinder has a radius R and height L0. The cylinder is open at its bottom and has a small hole at its top. A piston of mass M is held at a distance L from the top surface, as shown in the figure. The atmospheric pressure is P0.The piston is now pulled out slowly and held at a distance 2L from the top. The pressure in the cylinder between its top and the piston will then be

Air in a cylinder is suddenly compressed by a piston, which is then maintained at the same position, with the passage of timeA     The pressure decreasesB     The pressure increasesC     The pressure remain constant D     The pressure may increase depending upon the nature of the gas

A rigid, well-insulated cylinder is divided into two chambers bya fixed dividing wall. As the cylinder is well-insulated, heat transferoccurs only through the dividing wall: no heat is lost to thesurroundings. The first chamber contains 11 m3 of air at 800 kPa and0 °C. The second chamber contains 1 m3 of refrigerant R134a at 800kPa and 60 °C. The refrigerant is allowed to cool until the pressure ofthe R134a chamber reaches 600 kPa.a) Assuming air is an ideal gas, calculate the initial mass of air inthe chamber.b) Calculate the initial mass of R134a in the chamber.c) Considering the whole cylinder as the system, use the first lawof thermodynamics to derive a relationship between the internalenergy of the air and the internal energy of the refrigerant.d) Determine the temperature of the air chamber when the R134areaches 600 kPa.e) Has the system reached thermal equilibrium?

A gaseous air‑fuel mixture in a sealed car engine cylinder has an initial volume of 600.mL at 1.0atm. To prepare for ignition of the fuel, a piston moves within the cylinder, reducing the volume of the air‑fuel mixture to 50.mL at constant temperature. Assuming ideal behavior, what is the new pressure of the air‑fuel mixture?

15.Question 15A piston/cylinder system has an initial volume of 0.1 m^3 and contains nitrogen initially at 150 kPa, 25 °C. The piston compresses the nitrogen until the pressure reaches 1 MPa and the temperature is 150°C. During the compression process, heat is transferred from the nitrogen, and the work done on the nitrogen is 20 kJ. Determine the heat transfer of the process. The gas constant R for nitrogen is 0.2968 kJ/(kgK) and the specific heat c_v is 0.745 kJ/(kgK).1 point-8.4 kJ-4.2 kJ-3.7 kJ8.4 kJ
