A gas is taken through the cycle ABCA, as shown. What is the net work done by the gas?
-2000 J
2000 J
1000 J
Zero
As we learnt in
Work done in cyclic process -
It is the area under the cycle.
- wherein
Work is positive if cycle is clock wise. Work is negative if cycle is anti clock wise.
(for P - V diagram)
The given diagram is a P-V indicator diagram. Work done for P-V indicator diagram is area of the cycle.
Area of cycle
Work is positive as cycle is clockwise.
Correct option is 3.
Option 1)
-2000 J
This solution is incorrect.
Option 2)
2000 J
This solution is incorrect.
Option 3)
1000 J
This solution is correct.
Option 4)
Zero
This solution is incorrect.
