Question

Even under the most ideal conditions, only about 8% of the internal energy of the steam produced in a steam engine can be converted into actual work. What happens to the other 92% of the steam's available energy?

Answer 1

D) it is used in different parts of the steamboat.

Step-by-step explanation:

D because they're are other ways the energy would be transfered for other things on the boat. I THINK!

Answer 2

A) It is converted to heat energy.

Step-by-step explanation:

Although 25% of the steam's energy is turned into the work, the rest of the available energy, or 75%, is not. It is converted to heat energy. No machine can be 100% efficient and most of the energy is given off as heat energy. This is the reason that engines' temperatures rise when in use.
