Three samples of the same gas x, y and z, for which the ratio of specific heats is r=3/2, have initially the same volume. The volumes of each sample is doubled , by adiabatic process in the case x, by iosbaric process in the case of y and by isothermal process in the case of z. If the initial pressures of the samples x,y and z are in the ratio 2 sqrt2 :1 :2, then the ratio of their final pressure is

1.	Three samples of the same gas x, y and z, for which the ratio of specific heats is r=3/2, have initially the same volume. The volumes of each sample is doubled , by adiabatic process in the case x, by iosbaric process in the case of y and by isothermal process in the case of z. If the initial pressures of the samples x,y and z are in the ratio 2 sqrt2 :1 :2, then the ratio of their final pressure is
