Question
For an ideal gas, an illustration of three different paths 
and 
from an initial state 
to a final state 
is shown in the given figure
Path A represents a reversible isothermal expansion from 
to 
. Path 
represents a reversible adiabatic expansion (
) from 
to
followed by reversible heating the gas at constant volume (
) from 
to . Path represents a reversible expansion at constant pressure 
from 
to 
followed by a reversible cooling at constant volume 
from to
What is 
, for path 
?
The correct answer is:
According to the first law of thermodynamics
In isothermal process,
