Suppose someone claims they have invented a new automobile engine that can produce more energy than is found in the fuel used to run it. Apply scientific principles to evaluate the person's claim.

See explanation

Explanation:

According to the second law of thermodynamics, the conversion of energy  from one form to another is never hundred percent efficient. Some energy is always lost as energy is transformed from one form to another.

When a fuel is used to run an automobile engine, chemical energy from the fuel is converted into to the mechanical energy of the automobile. This energy conversion can never be hundred percent efficient in accordance with the laws of thermodynamics. Some energy is always lost as heat.

Hence, the engine does not even efficiently convert all the chemical energy available in the fuel. Therefore, it is impossible to find an automobile engine that can produce more energy than the fuel used to run it.
