An idealgass istaken fromstate A (Pressuer P, VolumeV) to the state B ( PressureP/2, Volume 2V)alonga strightline pathin PVdiagramas shown in the adjacentfigure . Selectthe correctstatement (s) amongthe following .

Answer»

<P>The WORKDONEBY gasin theprocessA to Bexceedsthe workthat
wouldbe done bygas in if the systemweretakenfrom A to B alongtheisotherm.
In The T- V diagram, the path AB become partof parabola.
In the P-T diagram, the path AB becomesa partof hyperbola.
Ingoingfrom A TOB, the temperature T of thegas first INCREASE to a maximumvaluethendecreases.

Solution :`(P- P_(0)) = ((P_(0)/(2)- P_(0)))/(2V_(0) - V_(0))(V_(0) - V_(0))`
` P = - ((1P_(0))/(2V_(0))) V +(3P_(0))/(2)`
