As shown in the figure below, a piston-cylinder assembly contains 1 kg of water at T1=200° C and P1 = 1.5 bar holding the piston against the stops. The atmospheric pressure is 1 bar, and you can assume the piston's weight is negligible. The water is slowly cooled until the piston just begins to move downward in the cylinder. What is the pressure (P2), temperature (T2), and volume (V2) of water at this point? (°C), V2 = P2 = (m³) The cooling continues until water has entirely turned into saturated liquid.

Consider the piston-cylinder. In the initial system, 1 mol of gas is in the state of 2 bar and 10 L. When the ring that fixed the piston was released, the expansion occurred and the final volume was 15.2 L. At this time, the external pressure is 1 bar. Seek what this system has done about aliens.

Figure 1 shows a piston-cylinder assembly containing gas, on top of a hot plate. At the beginning, the system is at room temperature, and the piston seats on the set of stops. Then, the heating plate is turned on and eventually the piston starts to rise. Determine at which pressure this happens, considering that g = 9.81 m/s 2.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.
