Physics Theory
The work done by a thermodynamic system during a process equals the area under the pressure-volume (PV) curve. For the D→E→F process:
D → E: Linear process → W = Area of triangle DEF = ½ × (P_D - P_E) × (V_E - V_D)
E → F: Isobaric process → W = P_E × (V_F - V_E) = P_E × (V_D - V_E)
The total work done is the sum of work done in both processes:
W_total = W_D→E + W_E→F
This simulation demonstrates how the work done corresponds to the area under the PV curve, with the D→E process forming a triangle and the E→F process forming a rectangle (or negative rectangle when volume decreases).
