According to 1st law of thermodynamics,
ΔQ = ΔU+ΔW
So for the vessel for which internal energy (and hence, temperature) remains constant
i.e.,
and for the vessel for which volume is kept constt.,
i.e.,
According to given problem
i.e.,
so
Now when the free mixing of gases is allowed
u1+u2 = u
With 
Here
and 
so 1 x 300 + 1 x 438.6 = 2T, i.e., T = 369.3 K
Further for the mixture from PV = μRT with V = V + 2V = 3V and μ = μ1 + μ2 = 2.
we have
ΔQ = ΔU+ΔW

The Combined System
The problem states that we have two vessels, each containing one mole of a monatomic ideal gas. The initial volume of the gas in each vessel is 8.3 * 10^-3 m^3 at a temperature of 27°C. The vessels are then connected to allow free mixing of the gas.
Equal Heat Supply
It is mentioned that an equal amount of heat is supplied to each vessel. This means that the change in internal energy of both vessels will be the same.
Expansion with Constant Internal Energy
In one of the vessels, the volume of the gas is doubled without any change in internal energy. This means that the heat supplied to this vessel is used only for expansion work, and not for increasing the internal energy of the gas.
Expansion at Constant Volume
In the second vessel, the volume of the gas is held constant. This means that the heat supplied to this vessel is used to increase the internal energy of the gas, as no expansion work is done.
Connecting the Vessels
After the expansion and heating processes in the two vessels, they are connected to allow free mixing of the gases. This means that the gases will reach a thermal equilibrium, where their temperatures and pressures will become equal.
Final Temperature of the Combined System
Since the amount of heat supplied to each vessel is the same, the change in internal energy of both vessels is the same. However, in one vessel, this change is used for expansion work, while in the other vessel, it is used to increase internal energy.
The vessel where the volume was doubled without change in internal energy will have a lower final temperature than the vessel where the volume was held constant. This is because the expansion work reduces the internal energy of the gas, resulting in a lower temperature.
When the vessels are connected, the gases will mix and reach a common final temperature. Since the gas from the vessel with constant volume has a higher initial temperature, it will transfer heat to the gas from the vessel with expansion. This will cause the temperature of the gas with expansion to increase and the temperature of the gas with constant volume to decrease.
Therefore, the final temperature of the combined system will be lower than the initial temperature of the constant volume vessel, but higher than the initial temperature of the expansion vessel.
Final Pressure of the Combined System
The problem does not provide any information about the pressure of the gases or any changes in pressure during the process. Therefore, it is not possible to determine the final pressure of the combined system based on the given information.
Conclusion
The correct answers are options A and C. The final temperature of the combined system is lower than the initial temperature of the vessel with constant volume, and the final pressure of the combined system cannot be determined with the given information.
