50 L of a certain liquid is confined in a piston system at the external pressure 100 atm. This pressure is suddenly released and liquid is expanded against the constant atmospheric pressure, volume of the liquid increases by 1 L and the final pressure on the liquid is 10 atm. Find the work done.
A
1L.atm
B
5 L.atm
C
500 L.atm
D
50 L.atm
Answer
1L.atm
Explanation
Solution
W = – Pext (V2–V1) = – 1 atm (1 L)
