Answer:
1. (A) 2%
Fuel efficiency is a form of thermal efficiency, indicating the ratio from the energy to result of a process that changes chemical potential energy held in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may change per device, which in turn may modify per application fuel efficiency.
2. (A) Carbon dioxide
Carbon dioxide is a colorless gas with a density of about 60% greater than that of dry air. Carbon dioxide carries a carbon atom contently double bonded to two oxygen atoms. It happens spontaneously in Earth's atmosphere as a trace gas.
3. (A) Fuel mileage and longevity
Car longevity is of concern to many car purchasers and interests different things: maximum service life in either mileage or time (duration), the connection of parts to this lifespan, classification of factors that might provide control in prolonging the lifespan.
Carrying a load of 100 pounds can reduce the car's fuel efficiency by 2%.
What do you mean by fuel efficiency?
Fuel efficiency may be defined as the amount of energy released per unit mass of the fuel.
One of the major harmful things that a car produces as it consumes gasoline is Carbon dioxide. Gasoline contains carbon and hydrogen atoms. During the combustion reaction, the carbon from the fuel combines with oxygen from the air, to synthesize carbon dioxide.
Assessing and monitoring your fluid levels will help you optimize your car's fuel mileage and longevity. Fuel mileage defines the average fuel with respect to distance, while longevity is the interest of many car owners that includes several other things.
Therefore, all the questions are above described one by one.
