The pV diagram in (Figure 1) shows the cycle followed by the gas in an ideal-gas heat engine. 260 J of heat energy flow into gas from the hot reservoir during process 1-2. V Correct Part B During process 3-1 does heat energy flow into the gas from the hot reservoir, flow out of the gas to the cold reservoir, or is no heat transferred? View Available Hint(s) O Heat flows in O Heat flows out O No heat is transferred Figure
