Question

A spring-loaded piston–cylinder device contains a mixture of gases whose pressure fractions are 25 percent Ne, 50 percent O2, and 25 percent N2. The piston diameter and spring are selected for this device such that the volume is 0.1 m3 when the pressure is 200 kPa and 1.0 m3 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 Ru = 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.
