A certain quantity of oxygen `(gamma=7//5)` is comparessed isothermally until its pressure is doubled `(P_(2))` . The gas is then allowed to expand adiabatically until its original valume is restored. Then the final pressure `(P_(3))` in terms of initial pressure `(P_(1))` is

A given mass of a gas is compressed isothermally untill its pressure is doubled. It is then allowed to expand adiabatically until its original volume is restored and its pressure is then found to be 0.75 of its initial pressure . The ratio of the specific heats of the gas is approximately .

A given mass of a gas is compressed isothermally until its pressure is doubled. It is then allowed to expand adiabatically until its original voume is restored and its pressure is then found to be 0.75 of its initial pressure. The ratio of the specific heats of the gas is approximately.

An ideal gas is compressed isothermally unit its pressure is doubled and then allowed to expand adiabatically to regain its original volume (gamma =1.4 and 2 ^(-1.4) = 0.38) The ratio of the final to initial pressure is

A monatomic gas is compressed adiabatically to (1)/(4)^(th) of its original volume , the final pressure of gas in terms of initial pressure P is

A monoatomic gas is compressed adiabatically to (1)/(4)^(th) of its original volume , the final pressure of gas in terms of initial pressure P is

A certain mass of gas is allowed to expand adiabatically to 6 times its original volume. Find the relation between the initial and final pressure. gamma=1.4 .
