Cyclic Thermodynamic Processes
22. The First Law of Thermodynamics / Cyclic Thermodynamic Processes / Problem 4
A thermal engine uses helium as the working fluid. At point A, helium is initially at a temperature of 300 K while the temperature at point C is 750 K. The pV diagram of the thermal engine's cyclic transformation is shown below. Calculate the heat Q during the transformation AB. Hint: Calculate W and ΔEint first.
