4- A heat engine receives heat from a heat source at 1200C and has a max. thermal efficiency of 40 percent. The heat engine does maximum work equal to 500 kJ. Determine the heat supplied to the heat engine by the heat source, the heat rejected to the heat sink, and the temperature of the heat sink. What does "max thermal efficient" mean, explain it verbally. (20p)
