Question

A spring-loaded piston–cylinder device contains a mixture of gases whose pressure fractions are 25 percent Ne, 50 percent O_{2}, and 25 percent N_{2}. The piston diameter and spring are selected for this device such that the volume is 0.1 m^{3} when the pressure is 200 kPa and 1.0 m^{3} when the pressure is 1000 kPa. Initially, the gas is added to this device until the pressure is 200 kPa and the temperature is 10°C. The device is now heated until the pressure is 550 kPa. Calculate the total work and heat transfer for this process. The universal gas constant is *R _{u}* = 8.314 kJ/kmol·K. Use the table containing the ideal-gas specific heats of various common gases and the table containing the molar mass, gas constant, and critical-point properties.

The total work for this process is _________kJ.

The heat transfer for this process is __________kJ.
