A frictionless piston/cylinder apparatus 100 mm in diameter contains water vapor with a quality of 20%. The piston, which has a mass of 16 kg, is floating on the vapor 50 mm above the bottom of the cylinder. Stops above the piston prevent it from moving upward more than 30 mm. Heat is added until the temperature reaches 400°C. Rather than interpolating for T₁ and ₁, you may assume the values are 105.1°C and 0.2837 m³/kg, respectively. Additionally, the saturated specific volumes at 121.26 kPa are 0.001048 m³/kg for saturated liquid and 1.414 m³/kg for saturated vapor. Find: a. the initial pressure b. the mass of water c. the quality when the piston hits the stops d. the final pressure of the water e. the work done by the water 4

Six grams of helium(4.0026 g/mol) undergoes an Isothermal process at 127 Celsius, beginning at 6 atm. Their container was found to be 0.04 meters under cube after the expansion. Assuming that helium unit is an ideal gas, calculate the amount of keep that flowed into or out of the helium during the process.

An oxygen tank has a volume of V = 3.00 m3. The gage pressure of oxygen in the tank is Pgage = 400.00 kPa. The room temperature is T = 27.00 ˚C and the atmospheric pressure is Patm = 100.00 kpa. The gas constant of oxygen is R = 0.25980 kPa/(kg·K). Oxygen can be treated as an ideal gas. Determine (2) the mass of oxygen, m =_____ kg
