9. Use the second law of thermodynamics to explain why energy cannot be recycled.?

Answer 1

The second law of thermodynamics is the concept of increasing entropy in the universe. Entropy is a measure of randomness, disorder and uniformity. With every energy change in the universe, there is an increase of entropy. All forms of energy, when used, are transformed into nonusable forms as their entropy increases. For example, when coal is burned, the gases released cannot be used as effectively. While energy cannot be destroyed, it can be converted to a form that cannot be reused.

Answer 2

Explain Thermodynamics

Answer 3

The second law of thermodynamics does not mean you cannot recycle energy. Heat energy is recycled all the time in many industrial and commercial applications. What the second law does say is that you can never recover and reuse all of the energy produced by the primary source.

Answer 4

The Second Law of Thermodynamics says that there is a limit to the efficiency of any heat engine. Heat is an essentially chaotic form of energy, the kinetic energy molecules moving randomly and no machine can convert this chaos completely into the ordered state needed for mechanical or electrical energy. Some energy will always be low-temperature heat. It is not possible to achieve 100% efficiency.

Answer 5

The concept of the second law is best stated using Max Planck’s description:

It is impossible to construct an engine that will work in a complete cycle and produce no other effect except the raising of a weight and the cooling of a heat reservoir.

Answer 6

Energy can't be recycled since heat is rejected from the initial system at a lower temperature than where it entered the initial system.

Answer 7

Because the oxygen has been used up!
