A gas expands in a piston cylinder device from volume `V_1` to `V_2`, the process being `p = a/V + b` where p = pressure, V = volume. The work done in the process is

A

`-a ln (V_1/V_2) + b(V_2 -V_1)`

B

`-a ln (V_2/V_1) -b (V_2-V_1)`

C

`-a ln (V_1/V_2) - b (V_2 - V_1)`

D

`a ln (V_1/V_2) + b(V_2-V_1)`

Starting with the same initial conditions an ideal gas expands from volume V_(1)" to "V_(2) in three different ways. The work done by the gas is W_(1) if the process is purely isothermal, W_(2) if purely isobaric and W_(3) if purely adiabatic. then

In the cyclic process shown on the V-p diagram, the magnitude of the work done is

A cylindrical vessel of unifrom cross-section consisting of a gas of gamma =1.5 is divided into two parts A and B using a piston. Intially the piston is kept fixed such that part A has pressure p and volume 5 v and the part B has pressure 8 p and volume V. If the piston is let free and the gas is allowed to undergo adiabatic process, then the final volume of the gas in part A is
