Constant Pressure for Maximum Work
Constant pressure is the condition that allows for the maximum work to be done by an expansion of a gas in a closed system. This is due to the fact that work done by a gas during expansion is given by the formula W = PΔV, where P is the pressure and ΔV is the change in volume.
Explanation
When the pressure is kept constant during expansion, the gas can do the maximum amount of work because the gas is able to push against a constant force (the pressure) as it expands. This allows for the gas to do work over a larger volume, resulting in more work being done overall.
Temperature, Volume, and Enthalpy
While temperature, volume, and enthalpy can also affect the work done by a gas during expansion, it is the constant pressure condition that allows for the maximum work to be achieved.
In conclusion, when looking to maximize the work done by an expansion of a gas in a closed system, it is important to keep the pressure constant. This will enable the gas to do the most work by pushing against a constant force as it expands.
