T2.5 Combustion outside the body

Learning goals

• I know the fire triangle
• I understand how a fire can be extinguished by removing one of the conditions in the fire triangle
• I know the combustion equation for complete combustion
• I know how incomplete combustion happens and I know what changes in the equation when it is incomplete combustion 
• I know the dangers of carbon monoxide (CO)

Key words

• Complete combustion
• Incomplete combustion 
• Fire triangle

Combustion

We learned that: 

• Combustion is burning
• Respiration is combustion in the body

It is also possible to combust things outside 

the body!

Can you list an example of combustion?

Conditions for combustion

Fire triangle - the 3 things needed for combustion:

• Fuel
• Sufficient oxygen to react with the fuel
• Sufficient heat for the reaction to begin

To put out a fire one of these things must be removed!

Putting out a fire

How are these fires put out?

Combustion equation

We know that fuel and oxygen are needed for fire, but what is created when something burns?

Incomplete combustion

Incomplete combustion happens if there is not enough oxygen or heat.

Carbon monoxide (CO) and carbon (C) are also produced:

• CO is a deadly invisible gas
• C is seen as soot, ashes or smoke

Short break

Please stay inside the classroom!

If you need to go to the toilet, you can ask me!
