Understanding Fuel for Transport

What type of fuel do airplanes use?

• Jet fuel

• Propane

• Gasoline

• Diesel fuel

Answer explanation

Airplanes primarily use aviation fuel, such as Jet A, Jet A-1, or avgas, which are specifically designed for aircraft engines. Propane, gasoline, and diesel are not suitable for aviation use.

What type of fuel do cars use?

• Gasoline or diesel

• Solar power

• Hydrogen

• Electricity

Answer explanation

Cars primarily use gasoline or diesel as fuel. These are the most common types of fuel for internal combustion engines, while other options like solar, hydrogen, and electricity are used in specific vehicle types.

From what resource do jet fuel and gasoline come?

• Crude oil

• Ethanol

• Coal

• Natural gas

Answer explanation

Jet fuel and gasoline are derived from crude oil, which is a natural resource that undergoes refining to produce these fuels. Ethanol, coal, and natural gas are different energy sources and do not produce jet fuel or gasoline.

Which uses more fuel, airplanes or cars?

• Cars use more fuel than airplanes.

• Airplanes use more fuel than cars.

• Airplanes and cars use the same amount of fuel.

• Airplanes use less fuel than cars.

Answer explanation

Airplanes consume significantly more fuel per mile than cars due to their size, weight, and the energy required to achieve flight. Therefore, the correct answer is that airplanes use more fuel than cars.

How do airplanes and cars differ in passenger capacity?

• Cars can carry hundreds of passengers, while airplanes usually carry 4 to 7.

• Airplanes can only carry 1 to 2 passengers, while cars can carry up to 10.

• Airplanes and cars have the same passenger capacity, typically around 5 to 6.

• Airplanes can carry hundreds of passengers, while cars usually carry 4 to 7.

Answer explanation

Airplanes are designed for mass transport and can carry hundreds of passengers, while cars typically accommodate 4 to 7 passengers, making the correct choice highlight the significant difference in capacity.

Why do cars burn through less fuel than airplanes?

• Airplanes use more fuel due to their heavier weight.

• Cars burn through less fuel than airplanes due to their design for efficiency at lower speeds and shorter distances.

• Airplanes are designed for efficiency at lower speeds.

• Cars have larger fuel tanks than airplanes.

Answer explanation

Cars are designed for efficiency at lower speeds and shorter distances, which allows them to burn through less fuel compared to airplanes that require more fuel for high-speed travel and longer distances.

What is one environmental benefit of carpooling?

• Reduced greenhouse gas emissions

• Increased traffic congestion

• Higher fuel consumption

• More air pollution

Answer explanation

Carpooling reduces the number of vehicles on the road, leading to fewer trips and lower fuel consumption. This results in reduced greenhouse gas emissions, making it an environmentally friendly choice.

Do airplanes travel longer distances than cars?

• Airplanes are limited to short distances compared to cars.

• Airplanes and cars travel the same distance.

• Cars can travel longer distances than airplanes.

• Yes, airplanes travel longer distances than cars.

Answer explanation

Yes, airplanes can cover much greater distances than cars due to their speed and ability to fly over obstacles. While cars are limited by road networks and traffic, airplanes can travel directly from one point to another over long distances.

Which mode of transport travels faster, airplanes or cars?

• Bicycles

• Boats

• Airplanes

• Trains

Answer explanation

Airplanes travel significantly faster than cars, typically reaching speeds of 500-600 mph, while cars average around 60 mph. Therefore, airplanes are the fastest mode of transport among the options provided.

How does the fuel consumption of airplanes compare to that of cars?

• Cars are always more fuel-efficient than airplanes regardless of load.

• Airplanes consume less fuel per passenger mile than cars.

• Airplanes use the same amount of fuel as cars when fully loaded.

• Airplanes generally consume more fuel per passenger mile than cars, but can be more efficient when fully loaded.

Answer explanation

Airplanes typically consume more fuel per passenger mile than cars due to their size and speed. However, when fully loaded, airplanes can achieve greater efficiency, making them more competitive in fuel consumption compared to cars.
