In a polytropic process, with the exponent n = k, where k is the specific heat ratio, 1.0 kg of neon (an ideal gas) in a friction-free piston-cylinder assembly expands from 400 k and 500 kpa to 100 kpa. for neon, ne = 20.18 kg/kmol and k = 5/3. sketch the system and the process. previously, you should have evaluated the work done by the gas in this process = kj now find the final temperature of the gas (using the polytropic formulas for ideal gases), and then find the change in internal energy for the process = kj
