Question

A car engine uses the combustion of fuel to move a system of gears that
move its wheels. Not all of the fuel's energy is transferred to the wheels,
Which two options describe what happens to the rest of the energy?
O A. Some energy is lost because it is transformed into chemical
energy
B. Some energy is lost because it is transformed into potential
energy
C. Some energy is lost because of the friction between the gears.
D D. Some energy is lost because it is transformed into thermal
energy
O E. Some energy is lost because it is absorbed by the driver

Answer 1

Answer: C and D

Explanation: I just took took the test

Answer 2

Answer:

The correct answers are C and D.

Explanation:

The friction of the car's moving parts rubbing up against each other and the thermal energy created by the combustion of the car's fuel both create heat that will take away from the energy from the fuel that is transferred to the car's wheels.

In short, some of the energy was not transferred to the wheels because the gears and the combustion create heat.
