n moles of an ideal gas undergo a process \[A\to B\]as shown in the figure. Maximum temperature of the gas during the process is                                                                                               [JEE ONLINE 12-05-2012]

A) \[\frac{8{{P}_{0}}{{V}_{0}}}{nR}\]    

B)      \[\frac{3{{P}_{0}}{{V}_{0}}}{2nR}\]

C) \[\frac{9{{P}_{0}}{{V}_{0}}}{2nR}\]  

D)      \[\frac{9{{P}_{0}}{{V}_{0}}}{4nR}\]

Correct Answer: B

Solution :

[b] Work done during the process

= Area of trapezium (= area bounded by indicator diagram with F-axis)

Ideal gas eqn : PV= nRT
