Question

An ideal gas is taken around the cycle ABCA as shown in P-V diagram. The net work done by the gas during the cycle is equal to :

A. `12P_(1)V_(1)`
B. `6P_(1)V_(1)`
C. `3P_(1)V_(1)`
D. `P_(1)V_(1)`

Answer 1

Correct Answer - C
The work done in the cyclic process
=Area bounded (ABCA)
`=(1)/(2)xxACxxAB`
`=(1)/(2)xx2V_(1)xx3P_(1)=3P_(1)V_(1)`.
