Which outcome occurs during the isothermal expansion phase of a Sterling engine?

💡 Explanation

The engine uses heat addition, causing isothermal expansion because the gas does work on the piston to increase the volume at constant temperature. Therefore option A is correct; rather than pressure or internal-energy relationships driving the process.
