Heat engine x has an efficiency of 67%. heat engine y has an efficiency of 82%. which best compares these two heat engines? heat engine x moves more thermal energy from cold to warm areas than heat engine y. heat engine x releases more energy to the surroundings than heat engine y. heat engine y releases more energy to the surroundings than heat engine y. heat engine y moves more thermal energy from cold to warm areas than heat engine x.

Respuesta :

Heat engine y releases more energy to the surroundings than heat engine y compares the two heat engines in a better way.

Heat Engine:                                                                                        

  • It mainly works by bringing the working substance from warmer temperature to lower temperature.
  • So, in the process of going through this cycle, the system performs some work on the surrounding. Then more work will be done by a more efficient engine.

In the question, it is said that x has an efficiency of 67% and y has an efficiency of 82%.

Therefore,  Heat  Engine y releases more energy to the surroundings than heat engine y. Hence, option (c) is correct.

Incorrect options:

     (a) It is incorrect because Heat engines work by taking heat from hotter regions to colder regions.

      (b) It is incorrect because the efficiency of x is less than y.

      (d) It is also incorrect because Heat engines work by taking heat from a hotter region to a colder one.
