    The piston is massless and the spring is ideal and initially stretched. The piston cylinder arrangement encloses an ideal gas. If the gas is heated quasistatically, the PV graph is

    A)  

    B)

    C)    

    D)

    Correct Answer: B

    Solution :

    [b] \[P={{P}_{0}}+\frac{kx}{A}\]                            ?...(i) \[V={{V}_{0}}+xA\]                                        ?...(ii) From equation (i) and (ii), \[(P-{{P}_{0}})\frac{A}{k}=(V-{{V}_{0}})\frac{1}{A}\] i.e., Pressure varies linearly with volume.
