Question

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

Answer 1

[AI-generated answer — Bot GPT 3.5]

1. The second law of thermodynamics states that it is impossible to achieve 100% energy efficiency in any system. Some of the energy will always be lost to heat, friction, and other inefficiencies in the car's engine and drivetrain.

2. The car's tires will always experience some level of rolling resistance, which means that not all of the energy from the fuel will be transferred to the road to move the car forward. This loss of energy will prevent the car from being 100% efficient.

3. Even if the car's engine and drivetrain were somehow able to achieve perfect efficiency, external factors such as air resistance and friction with the road surface will always cause some energy loss, preventing the car from being 100% efficient.
