Question

The figure show a PV diagram for an ideal gas. The path is isothermal (Delta T = 0). The change of internal energy' of the gas is positive, negative, or zero. The figure show a PV diagram for an ideal gas. The path is adiabatic (Q = 0). The change of internal energy of the gas is positive, negative, or zero. The figure shows a PV diagram for an ideal gas. Along the path, the gas returns to its original state. The change of internal energy of the gas is positive, negative, or zero. Two cyclic processes are shown in the PV diagrams for an ideal gas. Which cycle has the greatest thermal efficiency e = W eng/|Qh|? cycle A cycle B Both cycles have the same thermal efficiency.
