A steel cylinder initially contains nitrogen gas at 200kPa and 25oC. the cylinder is connected to a suply line containing nitrogen at 800kPa and 25oC. A valve is opened, allowing nitrogen to flow into the cylinder until the pressure reaches 800kPa. The cylinder internal volume is .1 m3 its mass(cylinder only) is 50 kg, and its specific heat is 0.43 kJ/kg*K. Find the final mass of nitrogen in the tank and the final temperature of the nitrogen assuming constant specific heats at room temperature for nitrogen, and

A.) no heat tranfer from the nitrogen to the tank, and

B.) rapid heat tranfer between the nitrogen and tank such that the cylinder and nitrogen remain in thermal equilibrium during the process (with negligable heat tranfer from the cylinder to its external surrounding.)
