Unconsciousness


We just learned about Consciousness.

Another part of sleep is Unconsciousness.

When a person is asleep they are usually not moving, with their eyes closed, and they can't talk or do things.
Sometimes a person gets hurt or passes out, and they look like they are asleep, but it's not really the same as being asleep because they can't just be woken up.
If someone is like this and they are still breathing and healthy but they seem asleep that is called being unconscious.

Sleep isn't the same thing as being unconscious because your body and brain are able to wake up if you need to.

Jet Fuel


We just learned about the Diesel Fuel.

Another thing that is made from oil is Jet Fuel, also called aviation turbine fuel, ATF, or avtur.

Jet fuel is a lot like diesel fuel, but because it has to be used for jet planes flighing high up in the air it has to be a little different.
When the jet goes up very high, it gets very cold so there can't be any water in the fuel or it could freeze.
It also has a very high flash point, which is the temperature that the air fumes start on fire.

Diesel Fuel


We just learned about Gasoline.

Another thing made from oil is Diesel Fuel.

Just like gasoline, diesel fuel can be used in cars and motors to make things go.
The big difference between gasoline and diesel is that diesel is thicker, and more like crude oil.

Gasoline is more easy to start on fire, so gasoline engines use a spark to light up the fuel,
but diesel engines use pressure to cause heat and make the diesel start on fire and run the engine.

Gasoline


We just learned about the Fluid Catalytic Cracking.

Turning oil from the ground into something we an use takes a lot of work and uses a lot of heating, cooling and mixing with chemicals.
When it is all done, there are a lot of things that oil is used for.

One of the most well known things we make from oil is Gasoline.

This is the fuel used for cars, airplanes, lawnmowers or any kind of a motor that burns gas.

Burning gasoline for fuel causes a lot of pollution, so there are a lot of people making electric cars to help make that better!
