A heat engine operates between 200 K and 100 K. In each cycle it takes 100 J from the hot reservoir, loses 25 J to the cold reservoir, and does 85 J of work. This heat engine violates: the second law but not the first law of thermodynamics O both the first and second laws of thermodynamics O the first law but not the second law of thermodynamics O neither the first law nor the second law of thermodynamics O cannot answer without knowing the mechanical equivalent of heat
