Answer:The sign of work will be negative.Explanation:The work of the system is given by:

Where:

: is the final volume = 31 L

: is the initial volume = 63 L

p: is the pressure

Even though we do not have the pressure value, by knowing the values of the initial and final volume we can predict the sign of work.

Therefore, the sign of work will be negative.I hope it helps you!
