Figure demonstrates a polytropic process (i.e.`PV^(n)` = constant ) for an ideal gas. The work done by the gas be in the process `AB` is

A

`(15)/(2) P_(0) V_(0)`

B

`(14)/(3)P_(0)V_(0)`

C

`8P_(0)V_(0)`

D

Insufficient information

Text Solution

Verified by Experts

The correct Answer is:
B

For a polytropic process `PV^(n)` = constant `implies 16 P_(0) V_(0)^(n) = P_(0)(2V_(0))^(n) implies "n"= 4`
Work done =`(P_(1)V_(1) - P_(2)V_(2))/(n-1) = (16P_(0)V_(0)- P_(0)(2V_(0)))/(4-1) = (14)/(3)P_(0)V_(0)`
