Just as no mechanical device can be 100% efficient, no heat engine can transfer 100% of its heat to a single object. some of the heat energy must be wasted (released into the environment). we have a heat engine that produces 150 j of heat, does 40 j of work, and emits 110 j into another system. what is the efficiency of the heat engine? show your work.
