Answer:
-205.49Joules
Explanation:
An adiabatic condition means no heat is gain or loss by the system during process.
The formula for calculating work done on the piston under adiabatic condition is W= -P∆V where;
W is the work done on the piston
P is the external pressure = 2.35atm
Since 1atm = 101,325pascal
2.35atm = 2.35×101325
= 238113.75Pascal
∆V is the change in volume = final volume - initial volume = 1.318L - 0.455L = 0.863L
If 1litre = 0.001m³
0.863litre = 0.000863m³
Substituting this values in the formula for calculating work done we will have;
Work done = -238113.7(0.000863)
Work done = -205.49Joules
The work done is negative because they assume the system is adiabatic i.e work is done on the surroundings by the system.
