An ideal gas expands in such a manner that its pressure and volume can be related by equation `PV^(2) = ` constant. During this process, the gas isA. heatedB. cooledC. neither heated nor cooledD. first heated and then cooled

Answer» Correct Answer - B
b. For an isothermal process, `PV =` constant and for the given process `PV^(2) =` constant.
Therefore has is cooled because volume expands by a greater exponent than is in an isothermal porcess.
