Question

An ideal gas expands in such a manner that its pressure and volume can be related by equation P V2= constant. During this process, the gas is (A) heated (B) cooled (C) neither heated nor cooled (D) first heated and then cooled

For an isothermal process, P V= constant and for the given process P V2= constant. Therefore the gas is cooled because volume expands by a greater exponent than in an isothermal process.

Q. An ideal gas expands in such a manner that its pressure and volume can be related by equation $P V^{2} =$ constant. During this process, the gas is

heated

cooled

neither heated nor cooled

first heated and then cooled

For an isothermal process, $P V =$ constant and for the given process $P V^{2} =$ constant.
Therefore the gas is cooled because volume expands by a greater exponent than in an isothermal process.
