    A sample of gas expands from \[{{\operatorname{V}}_{1}}\] to \[{{\operatorname{V}}_{2}}\]. In which of the following, the work dine will be greatest?    
                                                                                                                            [JEE ONLINE 25-04-2013]

    A)         Same in all processes

    B)       Isobaric process

    C) Isothermal process

    D)    A diabetic process  

    Correct Answer: B

    Solution :

    [b] Work done Area bounded by PV graph and volume axis
    Among the three process, bounded area by PV graph and volume axis is greatest for isobaric process, hence work done is greatest for isobaric process.
