148269 A given mass of gas is compressed isothermally until 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

148270 A monoatomic gas is suddenly compressed to $(1 / 8)^{\text {th }}$ of its initial volume adiabatically. The ratio of its final pressure of the initial pressure is (Given the ratio of the specific heats of the given gas to be $5 / 3$ )

148271 If energy is supplied to a gas isochorically, increase in internal energy is $\mathrm{dU}$ then :
