With coal or wood, the ash remaining after burning is lighter than the coal you start with. With natural gas, it turns to CO2 plus water vapor, so there is no fuel left. Similarly with oil, at least with light oil like kerosene or gasoline, it is all vaporised.

What is a gravity disc in fuel oil purifier?

A gravity disc in a fuel oil purifier is a component that helps separate water and sludge from the fuel oil. It works by using gravity to allow the heavier components to settle at the bottom of the purifier, while the lighter components rise to the top for removal. This process helps to clean and purify the fuel oil for more efficient use in engines.


What is released when fuel burns in oxygen?

Water is given off when fuels are burnt in oxygen


What happens if you light a lighter upside down?

If you light a lighter upside down, the flame will burn backwards toward the fuel source, which can be dangerous as it may cause the flame to reach the fuel compartment and potentially lead to an explosion. It is not safe to use a lighter in any orientation other than upright.


How does an electric cross lighter work to ignite flames without the need for fuel or traditional ignition methods?

An electric cross lighter uses a high-voltage electric current to create a spark that ignites the gas in the lighter, producing a flame without the need for fuel or traditional ignition methods.


How does weight affect the speed of a viehicle?

Weight affects the speed of a vehicle by influencing its acceleration and deceleration. A heavier vehicle typically accelerates more slowly and requires a longer distance to stop compared to a lighter vehicle. Additionally, a heavier vehicle may also experience increased tire wear and decreased fuel efficiency due to the added weight.

What's the difference between diesel and unleaded fuel?

Diesel fuel is heavier and oilier than unleaded fuel, and is used in diesel engines. Unleaded fuel is lighter and cleaner, and is used in gasoline engines. Diesel fuel is more energy-dense and efficient, while unleaded fuel burns cleaner and produces less pollution.


Why does a heavier plane fly further than a lighter plane?

It usually has greater capacity for fuel storage.


Is diesel fuel heavier than water?

Yes, diesel fuel is heavier than water. Water has a density of 1 gram per cubic centimeter, while diesel fuel has a density of about 0.85-0.90 grams per cubic centimeter. This means that diesel fuel will sink in water.


Why do engineers need to keep the masses of spacecrafts as low as possible?

The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.


What is heavier diesel fuel or water?

Water is heavier than diesel fuel


Why does the petrol fraction have a lower viscosity than the fuel oil fraction?

Petrol has a lower viscosity than fuel oil because petrol is a more refined product consisting of lighter hydrocarbons, while fuel oil contains heavier hydrocarbons and impurities. The lighter hydrocarbons in petrol flow more easily due to weaker intermolecular forces, resulting in lower viscosity compared to the heavier hydrocarbons in fuel oil.


What is the element mined to be the fuel in nuclear reactors?

We mine uranium for use as a nuclear fuel. The uranium is separated from ore, and may undergo enrichment to separate out the lighter U-235 nuclide from the heavier U-238 one.


What Fuel does a Star burn to create its own energy?

A star will use fusion to combine lighter atoms into heavier atoms. A main-sequence star (that's the majority of stars) will convert hydrogen-1 into helium-4, so in this case, hydrogen-1 is the fuel. Once it starts running out of hydrogen-1, it will start fusing the helium into heavier elements - in which case the main fuel will be the helium-4. Later in the life cycle of a star, the fuel can be even heavier elements.


Do you burn wood on the fire or in the fire?

Neither... The wood is the fuel, but first it needs to become a gas. The gas is what burns.


Is diesel gasoline a mixture?

No, diesel fuel is not a mixture of gasoline. Diesel fuel is a specific type of fuel that is heavier and less volatile than gasoline, and is used primarily in diesel engines. Gasoline, on the other hand, is a lighter and more volatile fuel that is used in spark-ignition engines.
