An ideal gas undergoes cyclic process `ABCDA` as shown in given `p-V` diagram. The amount of work done by the gas is

`6P_(0)V_(0)`

`-2P_(0)V_(0)`

`+2P_(0)V_(0)`

`+4P_(0)V_(0)`

Text Solution

Verified by Experts

The correct Answer is:

Work done =change in pressure `xx` change in volume =`(2P_(0)-P_(0))(3V_(0)-V_(0))=2P_(0)V_(0))`
since the cyclic process is anticlockwiese work done by the gas is negative i.e `-2P_(0)V_(0)`.
