question_answer

Which of the following is correct in terms of increasing work done for the same initial and final state [RPMT 1996]

A)            Adiabatic < Isothermal < Isobaric

B)            Isobaric < Adiabatic < Isothermal

C)            Adiabatic < Isobaric < Isothermal

D)            None of these

Correct Answer: A

Solution :

 In thermodynamic process, work done is equal to the area covered by the PV curve with volume axis. Hence, according to graph shown \[{{W}_{adiabatic}}<{{W}_{isothermal}}<{{W}_{isobaric}}\]
