This screenshot is from the Carnot Cycle page on Wikipedia. In the "Stages" section, it says that:
The gas expansion is propelled by absorption of heat energy, $Q_1$, and of entropy, $\Delta S=Q_1/T_1$ from the high temperature reservoir.
Why do they mention the second part about the entropy? They speak of it as though it is a second, distinct cause of the gas's expansion. It seems redundant to mention the entropy because during this isothermal stage, heat is increasing, yes, but that's already mentioned by "propelled by absoption of heat energy". Is it accurate the way it's written or nah?
