Aheat engine operates between a hot reservoir with a temperature of 400 k and a cold reservoir with a temperature of 300 k. the engine accepts 500 j of energy from the hot reservoir, does 150 j of work, and exhausts 350 j of energy into the cold reservoir.1)does this engine violate any laws of thermodynamics? it violates neither the first nor the second law of thermodynamics. it violates the first law of thermodynamics, but not the second. it violates the second law of thermodynamics, but not the first. it violates both the first and second laws of thermodynamics. can someone explain?
