To solve the problem of calculating the work done by a gas during isothermal and reversible expansion, we can follow these steps: ### Step 1: Understand the Process The question states that the gas expands isothermally and reversibly. Isothermal means that the temperature of the gas remains constant throughout the process. Reversible means that the process can be reversed without any change in the surroundings. ### Step 2: Use the Formula for Work Done The work done (W) by an ideal gas during an isothermal expansion can be calculated using the formula: \[ ...
