Answer to Question #52511 in Other Physics for john1x96
Two tanks are connected by a valve. One tank contains 2 kg of CO2 at 77°C and 0.7 atm. The other tank has 8 kg of the same gas at 27°C and 1.2 atm. The valve is opened and gases are allowed to mix while receiving energy by heat transfer from the surroundings. The final equilibrium temperature is 42°C. Using ideal gas model, determine: a) the final equilibrium pressure b) the heat transfer for the process.
