Heat And Thermodynamics

There are two identical containers C\(_1\) and C\(_2\) containing to identical gases. Gas in C\(_1\) is reduced to half of its original volume adiabatically, while the gas in container C\(_2\) is also reduced to half of its initial volume isothermally. Find the ratio of final pressure in these containers. (\(\gamma\) be the adiabatic constant).
