An insulated empty balloon is connected through a closed valve to a 90 L container, which is immersed in a thermostatic bath at 150°C. In the container, there is 0.3 kg of argon (M = 40, k = 5/3) at 400 kPa and 150°C. The envelope of the balloon exerts a pressure on its contents, which is directly proportional to its volume. The valve is opened and argon fl ows slowly into the balloon. When the pressures equalize, the valve is closed. Find

a. The final states in the balloon and the container. b. The heat and work interactions of the balloon. c. The change in entropy of everything involved in the process.
