2.12 A mass of 5 kg of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phàse and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20%. a) Determine the initial and final temperatures. b) Calculate the mass of liquid water when the piston first starts moving. c) Calculate the work done during this process. d) Show the process on a P-V diagram
0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. The gas then undergoes an isobaric process to a temperature of 260°C. What is the final pressure of the gas, in atm? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
