A rigid tank whose volume of 0.5 m3 initially contains ammonia at 20°C, 1.5 bar, and is connected by a valve to a supply line carrying ammonia at 12 bar, 60 °C. The valve is opened enough to allow more ammonia to enter, until the total mass of ammonia reaches 143.36 kg. The final temperature is 20°C. Calculate the heat transfer between the contents of the tank and the surroundings. Ignore the kinetic and potential energy variations.

Two tanks are connected by a valve. One tank contains 2.5 kg of nitrogen gas with the temperature and pressure of 100 °C and 80 kPa, respectively. The other tank contains 12 kg of the same gas at 30 °C and 1200 kPa. The valve is opened and the gases are allowed to mix the receiving energy by heat transfer to the surroundings. The final temperature is 48 °C. Determine the final equilibrium pressure.
