MAE 201: Example 4-9 #thermodynamics #equilibrium #ideal_gas

Thermodynamics: An Engineering Approach by Cengel Ex. 4-9: A piston–cylinder device initially contains 0.5 m3 of nitrogen gas at 400 kPa and 27oC. An electric heater within the device is turned on and is allowed to pass a current of 2 A for 5 min from a 120-V source. Nitrogen expands at constant pressure, and a heat loss of 2800 J occurs during the process. Determine the final temperature of nitrogen. Consider nitrogen an ideal gas.
