Two well insulated tanks of oxygen are connected together. The first tank has a volume of 16.8 L and starts off with the gas at pressure 1.75 atm and a temperature of 300K. The second tank has a volume of 22.4, but its gas starts off with a pressure of 2.25 atm at a temperature of 450K. When the valve is opened between the two tanks, what is the final temperature and pressure of the combined gas?

Two rigid tanks are connected by a valve.The left tank with a volume of 1.8m3 contains air at 28.1 C and 575 kPa while the right tank contains 4.2 kg of air at 33.3C and 410 kPa. Now the valve is opened and the air is allowed to mix until the system reaches thermal equilibrium with the surroundings at 13.8C. Determine the volume of the right tank and the final air pressure.

2. Consider a process in which two tanks A and B are connected by a valve. Tank A, which is insulated, has a volume of 600 liters and contains steam at 1.4 MPa, 300°C. Tank B, which is uninsulated, has a volume of 300 liters and contains steam at 200 kPa, 200°C. The valve connecting the two tanks is now opened and steam flows from A to B until the temperature in A reaches 250°C, at which time the valve...

Two thermally insulated vessels are connected by a narrow tube fitted with a valve that is initially closed as shown in the figure below. One vessel of volume V1 = 15.6 L, contains oxygen at a temperature of T1 = 295 K and a pressure of P1 = 1.76 atm. The other vessel of volume V2 = 23.0 L contains oxygen at a temperature of T2 = 435 K and a pressure of P2 = 2.10 atm. When the valve...

Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium (He) gas at 220 kPa, 40°C? The other tank initially contains 4.0 R of neon (Ne) gas at 150 kPa, sot. Now the valve is opened, allowing the two gases to mix with each other. Heat transfer occurs during the mixing process. The final equilibrium temperature is 44'C. The specific heats of monatomic gases are independent of temperature. Determine: (a) the final volume of...
