Build a thermodynamic cycle for 0.15 mol of ideal gas. Drag the state points, choose a preset engine, and account for W, Q, and ΔU on every leg. Sign convention: W is work done by the gas; Q is heat added to the gas.
Drag points to reshape the cycle (curved presets convert to straight legs when dragged). Straight legs are labeled isobaric / isochoric / linear automatically.
