Question

An insulated piston-cylinder device contains 100L of air at 400 kPa and 25°C. A paddle wheel within the cylinder is rotated until 15 kJ of work is done on the air while the pressure is held constant. Determine the final temperature (°C) of the air. Neglect the energy stored in the paddle wheel. 25------329.9-----O 145-----O 56.9
