Maximum work by an
expansion of a gas in a closed system is possible when process takes place at
constant
Pressure
Temperature
Volume
Enthalpy
Pressure
In p-V graph, if process is completely isobaric (constant pressure) then work done let W1. If process is completely isothermal (constant temperature) then work done let W2. If process is completely adiabatic (pvr = c ) then work done let W3.
Area under the curve in a p-V diagram is the work done.
Considering the graph shown above, area
under the curve (1) is more than (2) and (3).
Therefore, we can conclude that w1 > w2 > w3
Hence, the correct option is (A).
