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.

in a car engine, energy is converted in a number of ways to make the car run. identify the correct order of the energy conversion in the engine of the car by this path: the ignition switch is turned, which sends a signal to start the car by fuel burning. this gets the engine going, which produces heat. when the driver puts the car in drive and pushes the accelerator, the car starts moving. question 2 options: heat --> chemical --> mechanical --> electrical mechanical --> electrical --> heat --> chemical electrical --> chemical --> thermal --> mechanical chemical --> mechanical --> heat --> electrical
