Asteam engine absorbs 1.98 × 105 j and expels 1.49 × 105 j in each cycle. assume that all of the remaining energy is used to do work. a. what is the engine's efficiency? b. how much work is done in each cycle?

B) The heat absorbed by the engine is  while the heat expelled is , therefore the work done by the engine is the difference between the heat absorbed and the heat expelled:


a) The efficiency of the engine is the ratio between the work done by the engine and the heat absorbed, therefore:

The center is basically the heart of it

That would be kinetic energy
