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.

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 .

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 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 litre of hydrogen at 27^@C and 10^5 Nm^-2 pressure expand isothermally until its volume is doubled and then adiabatically until its volume is redoubled. Find the final pressure of the gas. 1(gamma = 1.4)

An ideal gas at 27^@C and a pressure of760 mm of mercury is compressed isotiiermally until its volume is halved. It is then expanded adiabatically to twice its original volume. If the value of gamma for the gas is 1.4. Calculate the final pressure and temperature of the gas.

A gass of given mass at a pressure of 10^(5)Nm^(-2) expands isothermally until its volume is doubled and then adiabatically until volume is again double. Find the final pressure of the gas. (gamma=1.4)
