An ideal gas expands isothermally from volume `V_(1)` to `V_(2)` and is then compressed to original volume `V_(1)` adiabatically. Initialy pressure is `P_(1)` and final pressure is `P_(3)`. The total work done is `W`. Then

A

`P_(3) gt P_(1) W gt 0`

B

`P_(3) lt P_(1) W lt 0`

C

`P_(3) gt P_(1) W lt 0`

D

`P_(3) = P_(1) W = 0`

Text Solution

Verified by Experts

The correct Answer is:
C

`implies W lt 0` & `P_(3) gt P_(1)`

A potato gun first a potato horizontally down a half-open cylinder of cross-sectional area A . When the gun is fired , the potato slug is at rest , the volume betweeen the end of the cylinder and the potato is V_(0) , and the pressure of the gas in this volume is P_(0) . The atmospheric pressure is P_("atm") . where P__(0) gt P_("atm") . The gas in the cylinder is diatomic, this means that C_(V) = (5R)/(2) and C_(P) = (7R)/(2) . The potato moves down the cylinder quickly enough that no heat is transferred to the gas. Friction between the potato and the barreel is negligible and no gas leaks around the potato . The parameters P_(0) , P_("atm"), V_(0) and A are fixed, but the overall length L of the barrel may be varied. The length L in this case is
