A gas may expand either adiabatically or isothermally. A number of p-V curves are drawn for the two process over different ranges of pressure and volume. It will be found that a) Two adiabatic curves do not intersect b) Two isothermal curves do not intersect c) An adiabatic curve and an isothermal curve may intersect d) The magnitude of the slope of an adiabatic curve is greater than the magnitude of the slope of an isothermal curve for the same values of pressure and volume

A gas may expands adiabatically or Isothermally. If P,V graphs are drawn and if s_(1) and s_(2) are the slope of the process then a) s_(1)gts_(2) b) adiabatic curve and Isothermal curve may intersect c) s_(1)lts_(2)

(A): The internal energy of an ideal gas does not change during an isothermal process (R ): In isothermal process product of pressure and volume is constant.

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 .
