An ideal gas with constant heat capacity...

An ideal gas with constant heat capacity `C_(V)=(3)/(2)nR` is made to carry out a cycle that is depicted by a triangle in the figure given below.

The following statement is true about the cycle-

A

The efficiency is given `1-(P_(1)V_(1))/(P_(2)V_(2))`

B

The efficiency is given by `1-(1)/(2)(P_(1)V_(1))/(P_(2)V_(2))`

C

Net heat absorbed in the cycle is `(P_(2)-P_(1))(V_(2)-V_(1))`

D

Heat absorbed in part AC is given by `2(P_(2)V_(2)-P_(1)V_(1)+(1)/(2)(P_(1)V_(2)-P_(2)V_(1))`
