help me with this asap A container is divided into two equal volumes by avery thin membrane. It is held at a fixedtemperature by immersion in a water bath. The lefthalf holds 1.1 mol of gas, and the right half holds2.2 mol of the same gas. The membrane is thenpunctured so that gas can flow freely between thetwo sides.rallaWhat is the change in the entropy of the system after the gas has come to equilibrium?Express your answer with the appropriate units.01μAAS = ValueUnits?

0.56 kg of water in a piston cylinder device as shown initially the water is at T, = 120 °C with volume V, = 36 L (State 1). Heat is then added such that all the water in the cylinder is saturated vapor and the piston just touched the spring without exerted any force on the spring (State 2). Then additional heat is added to the system such that the temperature is T, 600 °C and the pressure is P,= 400 kPa (State 3). 3 Po 3 1) Find the total work (from state 1 to state 3, in kW).

If 2900 KJ of heat is added to the ammonia until its final pressure and temperature are 413 KPa and 100C, respectively, what is the amount of work done by the fluid in KJ?
Water at P1 = 200 kPa with a quality of 25% has its temperature raised 20 oC (T2 = T1+20 0C) in a constant pressure process. What is the initial (v1) and final (v2) specific volumes?
The frictionless piston and cylinder contain 1 kg of water. The initial pressure and volume are each pressure of 100kPa 0.25 m^3 (state 1). The system was gradually heated and when the volume of water in the cylinder became four times the initial volume (state 2), the piston was fixed and heating was continued until the water pressure reached 300 kPa (state 3).

3. A piston is resting on stops in a frictionless piston-cylinder device. The system contains water with a mass of 1 kg. The initial temperature is 30°C and the initial volume is 0.1 m³. The pressure required to raise the piston is 100 kPa. Find the work done if we add heat until the water is completely vapor (x=1). Find the heat added to the system. Draw and label the process on P-v and T-v diagrams. 4. A frictionless piston-cylinder device contains 10 kg of water initially at 100 kPa and 100°C. If the volume reaches 20 m³, the piston hits a set of stops and is restrained from further upward travel. Heat is added until the temperature is 200°C. Calculate the pressure at this point. Also, calculate the temperature when the piston first touches, but exerts no force, on the stops. Draw and label the process on P-v and T-v diagrams.
An oxygen tank has a volume of 4 cubic meters and is at 20 degrees C and 700 kPa. The valve is opened, and some oxygen is released until the pressure in the Tank drops to 500 kPa.
