Final answer:
The amount of work done by a gas during expansion depends on the process of expansion. The work done by the gas would be greatest when the expansion is isobaric, meaning the pressure remains constant.
Step-by-step explanation:
The amount of work done by a gas during expansion depends on the process of expansion. In this case, the work done by the gas would be greatest when the expansion is isobaric, meaning the pressure remains constant. During an isobaric expansion, the work done by the gas can be calculated using the formula:
Work = Pressure x Change in Volume
By keeping the pressure constant, the gas is able to do more work as it expands.
