In changing the state of a gas adiabatically from an equilibrium state 
to another equilibrium state 
, an amount of work equal to 
is done on the system. If the gas is taken from state 
to 
via a process in which the net heat absorbed by the system is 
, how much is the net work done by the system in the latter case ?
Text Solution
Verified by ExpertsD
Given, work done, 
Work done is taken negative as work is done on the system.
In an adiabatic change, 
Using first law of thermodynamics,
For another process between state 
and state 
,
Heat absorbed 
Change in internal energy between two states via different paths are equal.
From first law of thermodynamics,
