(a)
Interpretation:
The work done in joules against the vacuum has to be calculated.
Concept Introduction:
At constant pressure, the exchange of heat between the system and surroundings is called as Enthalpy and its state function.
Enthalpy can be given by the formula,
Where, H=enthalpy
U=internal energy
P=Pressure
V=Volume
The work done on the system or by the system can be calculated from the equation
Where w=work done
P=Pressure
V=Change in volume
