In a thermally isolated system, two boxes filled with an ideal gas are connected by a valve. When the valve is in closed position, states of the box 1 and 2, respectively, are (1 atm, V, T) and (0.5 atm, 4V, T). When the valve is opened, the final pressure of the system is approximately

Two balloons A and B containing 0.2 mole and 0.1 mole of helium at room temperature and 2.0 atm, respectively, are connected. When equilibrium is established, the final pressure of He in the system is

Two thermally insulated vessels 1 and 2 are filled with air and connected by a short tube equipped with a valve. The volumes of the vessels, the pressures and temperature of air in them are know (V_1,p_1,T_1 and V_2,p_2,T_2 ). Find the air temperature and pressure established after the opening of the valve.

Two containers C1 and C2 of volumes V and 4V respevtively hold the same ideal gas and are connected by a thin horizontal tube of negligible volume with a valve which is initially closed. The initial pressures of the gas in C1 and C2 are P and 5P, respectively. Heat baths are employed to maintain the temperatures in the containers at 300 K and 400 K respectively. The valve is now opened. Select the correct statement:

Two thermally insulated vessels are filled with an ideal gas. The pressure, volume and temperature in the two vessels are P_(1), V_(1), T_(1) and P_(2), V_(2), T_(2) respectively. Now, the two vessels are connected using a short insulating tube. (a) Find final temperature of the gas. (b) Express the final pressure of the gas in terms of P_(1), V_(1), P_(2) and V_(2) only.

Two heat proof containers of volumes 1L and 2L are connected by a tube.Keeping the valve attached to the tube closed,the 1st container is filled with nitrogen at 0^@C and at 0.5 standard atmosphere pressure, and the 2nd container with argon at 100^@C and 1.5 standard atmosphere pressure. The temperature of the gas mixture becomes 79^@C when the valve is opened,find the pressure of the gas mixture.

A container with insulating walls is divided into two equal parts by a partition fitted with a valve. One part is filled with an ideal gas at a pressure P and temperature T, whereas the other part is completely evacuated . If the valve is suddenly opened, the pressure and temperature of the gas will be
