A gas expands in a frictionless piston-cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of 100 kPa. During the expansion process, the pressure of the system (gas) remains constant at 300 kPa. The change in volume of the gas is 0.01 m3. The maximum amount of work that could be utilized from the above process is.

Given Data:
- Ambient Pressure (P1) = 100 kPa
- System Pressure (P2) = 300 kPa
- Change in Volume (∆V) = 0.01 m3

Calculating Work Done:
- The work done during an isobaric process (constant pressure) is given by the formula:
\[ W = P \times ∆V \]
- Where P is the pressure of the system.

Substitute the given values in the formula:
\[ W = 300 \times 0.01 = 3 kJ \]
Therefore, the maximum amount of work that could be utilized from the above process is 3 kJ, which corresponds to option 'C'.
