Answer: Option (e) is the correct answer.
Explanation:
The given data is as follows.
Volume = 140 , Pressure = 7600 Pa
q = 490 kJ, = 140 kJ
As we know that relation between internal energy and work is as follows.
140 kJ = 490 kJ + w
w = (140 - 490) kJ
= -350 kJ
Now, calculate the final volume using work, pressure and volume change relationship as follows.
w =
-350 kJ =
(As, 1 J = )
Which is nearest to 190 .
Thus, we can conclude that the final volume of the cell is 190 .
