Slide 4 - Slide

T2.5 Combustion outside the body

Slide 5 - Slide

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)

Slide 6 - Slide

Key words
  • Complete combustion
  • Incomplete combustion 
  • Fire triangle

Slide 7 - Slide

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?

Slide 8 - Slide

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!

Slide 9 - Slide

Putting out a fire
How are these fires put out?

Slide 10 - Slide

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

Slide 11 - Slide

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

Homework
Make question 43-55 in your textbook (pages 86-89)
