2 moles of He are mixed with 2 moles of {H}_{2} in a closed adiabatic container. Initially the mixture occupies 3 litres at 27^{\circ} {C}. The volume is suddenly decreased to (\frac{3}{2}) liters. Choose the correct option(s): ( {H}_{2} and He can be treated as ideal gases):

\gamma for mixture is \frac{3}{2}

Final temperature =300 \sqrt{2} {K}

Work done in compression is totally converted into internal energy.
