Heat engine work output

A heat engine in a piston gas investigation absorbs \(575\,\text{J}\) from a hot reservoir and rejects \(360\,\text{J}\) to a cold reservoir. Calculate the work output. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
