2 mol of He gas initially at STP are sealed in a cylinder with a movable piston. Heat is extracted from the gas until it reaches a temperature of 100 K. Then the piston is locked in place, and 9000J of heat are added to the gas. Finally, the pin is removed and the gas expands very very quickly to its initial volume.

What is the thermal efficiency of this engine?
