Two moles of an ideal monoatomic gas at temperature T are mixed thermally with six moles of another ideal monoatomic gas at temperature 2T. Assuming no heat is exchanged with the surroundings and both gases have the same molar heat capacity at constant volume, what is the final equilibrium temperature of the mixture?
