Question

Some cars are 100 percent efficient at converting energy from gasoline to energy of motion.
a. True
b. False

Answer 1

Some cars are 100 percent efficient at converting energy from gasoline to energy of motion.
This is a false statement.

Answer 2

The statement that some cars are 100 percent efficient at converting energy from gasoline to energy of motion is false.

In this case energy conversion is the transformation of energy from forms provided by nature (gasoline) to forms that can be used by humans (motion).

The efficiency of these systems is limited, because it is dictated by the laws of thermodynamics and other scientific principles. So, 100% efficiency is not possible.
