3. Three samples of the same idcal gas (the ratio of heat capacitiesγ = 1.5) have equal volumes andtemperatures. The volume of each sample is doubled, the process being isothermal, adiabatic, andisobaric, respectively. If the final pressures are equal for the three samples, the ratio of their initialpressure is
(A) 1:1:1,
(B) 2:2:1,
(C) 1:2:1,
