A rigid tank of volume 0.018 m is connected through a closed valve to a vertical cylinder fittedwith a freely moveable frictionless heavy piston of area 0.02 m?. Initially, the rigid tank is filled withair at 500 kPa and 25 °C while the cylinder has air of volume 0.015 m³ at 25 °C. In the vicinity, theambient air pressure is 100 kPa and the gravitational acceleration is 9.81 m/s. It is given that the2air can be assumed to behave as an ideal gas with the gas constant R = 0.287 kJ/kg.K.(a) At this initial state, determine the air pressure in the cylinder.The valve is then slowly opened and left opened, allowing the pressurised air from the rigid tank toflow gently into the cylinder, thus lifting the piston. This process continues until the piston comesto rest with the whole connected system reaching its final state of equilibrium. During this entireprocess, the air temperature in the rigid tank and the cylinder remains constant at 25 °C.(b) Find the mass of the air transferred from the rigid tank to the cylinder(c)Calculate the displacement of the piston during this process(d) Find the work done by the air in the connected system during the process.

Need help with this book problem using thermodynamics Nitrogen gas at constant pipeline conditions of 200 kPa and 300 K passes slowly through a valve into a well-insulated, frictionless, and initially evacuated piston-cylinder assembly. A pressure of 150 kPa in the cylinder is needed to support the piston due to its own weight and the ambient atmosphere. The volume under the piston is 1 m3 at the end of the process. Find (a) the boundary work done during this process, (b) the final temperature of the nitrogen in the cylinder, and (c) the mass that enters the cylinder during the process.

An airtight dispenser for drinking water is 25 cm × 10 cm in horizontal dimensions and 20 cm tall. It has a tap of negligible volume that opens at the level of the bottom of the dispenser. Initially, it contains water to alevel 3.0 cm from the top and air at the ambient pressure, 1.00 atm, from there to the top. When the tap is opened, water will flow out until the gauge pressure at the bottom of the dispenser, and thus at the opening of the tap, is 0. What volume of water flows out? Assume the temperature is constant, the dispenser is perfectly rigid, and the water has a constant density of 1000 kg/m3
