A) A car company claims that it has designed a new car that is 100% efficient. It says that 100% of the energy in the fuel is used to make the car move. State three reasons this is impossible (3 points)
B
) The laws of thermodynamics state that it is impossible to achieve 100% efficiency in any system. Some energy will always be lost in the form of heat, sound, or friction.
2) Internal combustion engines, which are commonly used in cars, are typically only about 25-30% efficient. This means that even with the most advanced technology, it would be impossible to achieve 100% efficiency.
3) The transmission of power from the engine to the wheels, as well as other mechanical components of the car, will always result in some energy loss. No system can be completely frictionless, so some energy will always be wasted in the process of making the car move.
