Extracted text: Very good system. There is a 100 It capacity capacitive 25°C nitrogen gas at 200 kPa pressure. This valve throttles in electricity consumption at 90°C. The connection is opened and the pressure in the container is filled with its use until it becomes 400 kPa. Find the final temperature and total entropy in the container with constant specific heats. NOTE: The quadratic solution with ax2+bx+c=0 is c=0; -b + vb2 – 4ac x = 2a
